DEVICE FOR PROCESSING STORED TEXT CODE SEQUENCES FOR THE PURPOSE OF FORMING TEXT BLOCKS OF DIFFERENT FORMATES

The invention relates to a device for processing stored text code sequences for the purpose of forming text blocks different formats according to the preamble of claim 1.

The processing of text codes stored in a memory according to predetermined format parameters, including It is well known that tab codes and excluded right margins without printing the formatted text and, for example, in U.S. Patent No. 3,991,405. In the case of an exclusion operation, the number of step codes accumulated in the memory is compared with a predetermined number Number for the right edge minus the width of the so-called hot zone, a control circuit is provided. Before reaching carriage return codes occurring during a comparison replaced by erasure codes or spacing codes. In the hot zone, a carriage return code is placed in the position of the last correct line ending there. If this is not possible, the control circuit enables an output device to print out the entire hot zone encompassing word. In this expression both the number of the line in which this non-conditional expression occurs, as well as an indication for the operator whether the word is the last word of a paragraph.

If a tab code is sensed during this edit a circuit is provided for calculating the space that will be used during the final printout by the printer is needed for the correct setting of the tab code. The calculation is carried out by counting the character positions between corresponding tab codes in the electronic tab section. The number of character codes and control codes, as well as the tabulation code, which are to be included in the line, is accordingly reduced by the space that is available for the execution of the tab code is required by the printer or other output device.

Conventional devices as described above can do complex text formatting work, for example Execute only to a limited extent in the typesetting industry. There, text on a page can be excluded text blocks of different Line length, commonly known as wrap around, included to allow for the insertion of images or other material, that does not consist of text. Also allow Conventional text formatting devices allow the operator to query the memory for a given line of text and the beginning of the text formatting after the queried line in different format codes than those of the previous one Text not. Finally, conventional institutions do not provide for the possibility of text editing for different Interrupt special codes that can be stored with the text. The operator does not receive enough information either for determining the cause of the interruption and entering information into the system while correct line endings be followed without another scan, and then returning to edit mode are not possible.

In Fig. 1, a word processing device is shown, which consists of a printer 2, a keyboard 3 and a memory 4 consists of a data bus line 13, a control bus line 15 and a decoding bus line 17 with the Control logic 1 are connected. This control logic contains the keyboard circuit 5, the printer circuit 7, the shift register control and decoding circuit 6 and a playless text processing controller 8. The memory 4 can be a circulating shift register memory including the shift register control and decoding circuit 6 known Be of the type, for example, in the US patent No. 3,675,216.

In Fig. 2, the shift register control and decoding circuit 6 is shown in detail. It is essentially the same as Fig. 4 of the above-mentioned patent. The control signals A, B, C and D control the flow of data from the circulating memory 4 through the shift register control and decoding circuit 6 and back into the circulating memory 4. The control signals A, B, C and D also control the path of the

AT9-77-007

Data, which are controlled in the circular memory, in the circular memory used or deleted in the circular memory. The exact manipulation of the control signals for execution the various operations are described in the above-mentioned patent. In short, the data is running from the circulating memory 4 through the signal lines 40 into the input register 44. From the input register 44, the Data are given to the data bus line 13 by applying a positive control signal A to the AND gate 47. During normal operation, the signal D on line 55 is at a logic one level to indicate the contents of the Input register 44 via the data line 51 through the AND gate 52 into the normal register 61. The content of the normal register 61 is passed through the AND gate 76 by a logic zero signal B, which is from the inverter 71 is inverted, and a logic zero signal C, which is inverted by the inverter 73. The content of the normal register is entered through the AND gate 76 into the output register 83 and through the data lines 84 into the circular memory 4 returned.

Data can be set from the data bus 13 into the circular memory 4 by using the signals B and C raises to a logical one level and thereby the AND gate 81 for routing the data from the data bus initiated via the data line 50 in the output register 83. Those in normal register 61 at this time Data is saved in the input register 66 and the next character in the input register 44 is in the normal register 61 shifted. This technique adds one character to the capacity of the shift register memory.

After entering the character from the data bus 13, the signal C is dropped to a logic zero level and the signal B remains at a logic 1, whereby together with the inversion of the signal C from the inverter 73, the AND gate 85 shows the contents of the input register 66 in the output register 83 conducts. Data continues to run on this

909837/0643

BATH ORIGINAL

AT9-77-007

Way through the input register 66 until a character is in the input register 44 stands to be deleted from the memory. After the next two data shifts, signal B becomes dropped to a logic zero level and thereby the character to be deleted is held in the input register 66. Signal D remains at logic 1 and passes data from input register 44 into the normal register and logic Zero signals on lines B and C are inverted to operate AND gate 76 and carry data from the normal Register 61 in the output register 83. The shift register control is thus returned to the normal state, by eliminating the shift register memory expansion by 1 character.

Fig. 3 shows the logic flow in the word processing system of the interactive editing process without playback. Assuming the operator is the facility wants to operate in edit mode without playback, then she presses a key on the keyboard 3 for a query, which puts the system into the area input mode 9 by a signal on the data line 13. Included the operator is requested to enter a number representing the number of lines to be processed. After this the range entry is made, the system goes into the active query mode 10, with the existing in memory Text characters processed according to the specified formatting parameters including operating mode and dimension parameters will. The operating parameter determines the type of formatting operation, e.g. line exclusion, left-justified, staggered on the right, and the measure parameter is the entire step set for each line of text. When the system is in active Inquiry operation 10 encounters an interrupt code, line overflow, or determines that the range entry number has been reached, it triggers a reference pressure 11, whereby the operator a visual display for the occurrence an interruption, the type of interruption and the location of the interruption in the text. If the sub-

Refraction triggered by reaching the area entry number the reference print consists of the display of the last edited line of text. There is a in front of the line Line number and a special character that it designates as the "last line". If the interruption is due to some other cause is triggered, e.g. a stop code, an output code, an error, a line overflow or a page end code in the text, then the system goes to the interrogation pause 12 after the reference print. Now the operator can enter further information into the system or print out text from the memory and / or the active Resume the interrogation process.

Referring to FIG. 1, it is now assumed that the circular memory 4 is provided with a sequence of text codes accordingly Lines and paragraphs of an input text from the keyboard or another suitable input / output device, such as a magnetic tape or disk file. Before starting an editing process without playback operating mode and dimension information must be saved in the system. The mass information is stored in a mass register 160 (FIG. 7), which consists of a random memory as described in U.S. Patent 3,991,405. It contains a separate bit storage location for each character print position on the print line of the printer 2. How the random memory works is described in detail in the above-mentioned patent specification. Tab stops can be saved in the dimension register that one lets the printer carriage of the printer advance to a desired tabulator position and presses a tab key on the keyboard. This sets a bit in the memory location in the random memory, which corresponds to the position selected on the keyboard 3 in the printer. By pressing the tabulator key, a MODEC signal from character decoder 56 put on line. This decoded signal operates a character shift register 316 and the AND gate 318, so that the

909857/0643

AT9-77-007

Subsequent tabulator code is passed into the binary decoder 240 will. The output of the binary decoder 240 then places the correct tab information in the measure register 160. The right margin is saved in the dimension register 16 0 by moving the printer carriage to the desired position on the right Rand sets and enters a carriage return. The difference between the left and right margin is then used for the calculation the total step length of the printed line of text is used. Information about the operating mode, dimensions and tab stops also stored in memory 4 as a sequence of codes that allow subsequent output formatting of the text without Operator intervention permitted.

AREA ENTRY MODE

As shown in FIG. 7, a signal is given to the data bus line 13 when the operator presses an interrogation request key the keyboard 3 presses. This signal (ABFR. ANF.) Is decoded by the character decoder 56 and routed to the query request line 33. It serves as an input to the AND gate 62 and shown in FIG. 6 is forwarded over a line 31 to set the range input switch 98 when the signal SP. EMPTY on line 35 (memory not empty) and the signal ABFR. (System not in query mode) on line 77 occur simultaneously. The signal SP. EMPTY on line 35 indicates that the circulating memory 4 is not empty, and is output from a memory sensor 258 in FIG. 9 which, by interrogating the decoding bus 17, determines whether the circular memory contains 4 data characters. When the circulating storage 4 contains no data, the signal is SP. EMPTY on logical 1. Therefore press the REQUEST signal. ANF. 33 and ABFR.77 together the AND gate 260, whereby the switch 262 is set. The output of switch 262 causes then the controller 702 to control the printer and to print the letters EM, whereby the operator is

shows that the memory is empty. This signal will from inverter 238 to signal SP. EMPTY inverted. The signal ABFR. on the line 77 is derived from the NOR element 80, at the inputs of which the following signals from the operating mode switches shown in Fig. 6 are applied: BER.INP. 38 (Range entry), CURRENT REQUEST. 57 (Active query), REF PRINT 115 (reference pressure) and ABFR. PAUSE 119 (interrogation pause). Since none of these operating modes were switched on earlier, are all inputs to the NOR gate 80 to logic 0 and the signal REQUEST on line 77 is a logical 1.

The signal BER.INP.ON on line 31 passes through the OR gate 140 and via the line 89 and sets the switch 142 shown in FIG. 5 for a range indication. The signal also resets switch 138 and counter 132. The signal REPORT NOTE on line 91 initiated then the print register 18 to give signals on the control bus 15 and the data bus 13 so the printer 2 executes a carriage return and prints out a note to the operator, who asks them to Enter a number on the keyboard indicating the number of lines of text to be edited. In the exemplary embodiment the note consists of a carriage return, the small letter c and a dash. When printing is finished, so a signal comes back on line 131 and resets switch 142. The PRINT END signal on the line 131 runs together with the signal BER.NWEIS on the line 91 through the AND gate 152, sets the switch 154 and generates a logical ones signal RNGDTA on line 93. This signal controls the entry of the area number into the system from the keyboard. The system is now ready to enter the area number via the keyboard. When a key on the keyboard is pressed, the The signal representing the character from the keyboard is applied to the data bus 13, decoded by the character decoder 56 and output the corresponding decoding. If it is a print mark and not a

Control character, the signal DR.Z. on line 39 a logical 1. If the keyed character is also a number, then the ZZ signal is also on the line 63 is a logical 1. In FIG. 5 it is shown how the signal RNGDTA on the line 93 corresponds to the signal ZZ on the line 6 3 through AND gate 130 to increment counter 132 by one. The signal RNGDTA on line 93 conducts also the signal DR.Z. on line 39 through AND gate 148 to turn on pressure enable switch 150 so the print trigger circuit 703 prints the character keyed in the keyboard 3. The pressure release switch 150 is reset by a signal from the print trigger circuit indicating that the character has been printed. Of the Switch 138 was activated by the signal RANGE INPUT ON on the Line 31 is reset as described above via the OR gate 140 and the signal KEIN ZZ on line 129 stands on logical 1.

As shown in Figure 4, the RNGDTA signal on line 93 carries the keyed-in character from the data bus 13 through AND gate 106 into binary decoder 108. The output of counter 132 (FIG. 5) is taken from the decoder 134 is decoded to provide an output indicating the next digit to be keyed in. The counter 132 was previously cleared by the signal BER.INW.EIN 89, whereby the NUMBER 1 line 101 was seized. The signal NUMBER 1 is actuated together with the signal ZZ as shown in FIG the gate 110 and forwards the contents of the binary decoder 108 into the register 112. The contents of the binary decoder 108 is also transmitted to adder 116 via signal line 95. The signals NUMBER 1 and ZZ control the AND gate 124 so that it is the content of the binary decoder 108 via the AND gate 124 and the OR gate 120 in the register 122 directs. The output of register 122 is that indicated by the ABFR.BER signal. Interrogation area specified on line 105. The signal REQUEST. on line 105 is decoded by decoder 126 to a signal on line 107,

that indicates whether the number entered for the query area is 0. This signal becomes one from the inverter 128 Signal on line 109 inverted, which indicates that the interrogation range is different from 0.

The binary decoding of the first into register 112. The transmitted character is the input to the tens multiplier 114 which multiplies the signal by 10 and becomes a Output on line 9 7 generated. Thus ten times the binary decoding of the entered number becomes binary Decoding of the number entered in the adder 116 is added and the sum is added to the one leading to the AND gate 118 Line 99 generated. An entry of this signal into the interrogation area register 122 is prevented because the Signal NUMBER 2 on line 103 is at logic 0 when the signal ZZ on line 6 3 is at logic 1 at the beginning stands.

When a second digit is entered from the keyboard it is passed through AND gate 106 and from Binary decoder 108 is decoded. The NUMBER 2 signal on line 103 was caused by the previous decoding 134 of the output of the counter 132 is raised. This second number decoding is then ten times the first number from adder 116 adds and generates a sum that replaces the previous sum on line 99, which was caused by the NUMBER 2 signal on the Line 103 and the signal ZZ on line 63 via the AND gate 118 and the OR gate 120 and the Forms query area in register 122. This signal is again decoded by decoder 126 as described above. The character is also forwarded to the printer logic 7 as described above for printing.

In the present exemplary embodiment, the system does not accept an area number that has more than two digits. if A third digit is entered, then a signal for a more than two-digit number is on the line 125 of the decoder 134 is raised to logic 1. This character is also printed as described above. if

but a carriage return is entered indicating the end of the line, a signal is sent on line 19 through the Decoder 56 in Fig. 7 raised and the AND gate 144 gives a signal NEWNOTE on the line via the OR gate 140 133, so that the area notification switch 142 controls the printer via the register 18 to operate for input to assign a new area number. If a non-number character is entered during the area entry operation, then the signal ZZ on line 63 is at the logic zero level. Since no line end signal entered was, the signal on line 19 from decoder 56 is also at logic 0, and the END OF LINE signal is on line 29 to logic 1. The switch 138 is set by the AND element 136 and outputs a logic one signal KEIN ZZ on line 127. If an end-of-line character (e.g. carriage return) is then keyed in, the END OF LINE on the line 19 logical 1 and the signal KEIN ZZ on the line 127 runs through the OR gate 146 and gives the Signal on line 133 through AND gate 144, causing the printer to respond to the input of an operator again indicates new area.

If it is now assumed in connection with FIG. 11 that the area input switch 98 of FIG. 6 is set to the area input mode, is set as described above, the signal RANGE INPUT. an input on line 38 to AND gate 306. If the operator presses a line back key on keyboard 3 (FIG. 1), it will Signal is decoded by character decoder 56 to a logical ones signal on line 21 in FIG. This ROW BACK signal. on the line 21 is transmitted to the OR gate 304 of FIG. 11, thanks to the signal BER.INP. on line 38 through AND gate 306 to OR gate 312 to set switch 314. Same Operation is triggered by the OR gate 302 when the operator presses the key, paragraph feed, top of page or press line feed. This makes a logical one

Generates a signal on line 135 which is sent to the printer logic 7 is transmitted to ring the bell in the printer. The signal FEHL is also through the OR gate 78 in 6 on line 42 to reset switch 98 and the system out of area entry mode. take out.

ACTIVE INQUIRY

It is assumed that the operator correctly uses a one-digit or two-digit range number other than 0 entered the system and keyed in a carriage return. Then the query area is now in register 122 of the 4 and the signal ABFR.BER. = 0 on the line 107 is a logic 0, while the signal ABFR.BER. = 0 on the line 109 is a logical 1.

The combination according to FIG. 6 of the signal ABFR.BER. = 0 on line 109 with the keyed-in line-terminating carriage return on line 19 is enabled by the signal BER.IN. on line 38 from switch 98 via the AND gate 26 and the OR gate 68 and a signal AKT.ABFR.EIN on line 59 is generated. This signal on the Line 59 forms an input to the interrogation switch 102 for generating a signal AKT.ABFR. on line 57. That The ACT.REQUIRED ON signal on 59 is also triggered by the OR gate 78 to reset the range entry switch 98 on line 42. The ACT.REQUIRED ON signal on the line 59 is also used to set the automatic switch 284 in FIG. 10 to output an automatic signal AUTO on the Line 283. The system is now in active query mode.

According to the representations in FIGS. 7 and 8, editing is ended immediately without playback, if none beforehand Format dimension has been entered and the first codes read in the memory are not parameters for the document formatting. The output 137 of decoder 162 of measure register 160

AT9-77-007

is at logic 0 and the signal AKT.ABFR. on the line 57 to logical 1. If the character decoded by the decoding 56 in Fig. 7 is not a document format parameter (DFP) is, then, the DFP on the line 45 is logical 1. This causes the AND gate 232 to generate a signal ABBR. . operated on line 241. The CANCEL signal. sets the switch 314 in FIG. 11 so that the machining operation is canceled without playback as described above. When the characters first read from memory are formatting parameters then DFP is at logic 0, MODEC is at logic 1 and shows the decoding of an operating mode code on and the measure is given by the data stored in the memory. The mass information codes follow the Mode code in circular memory 4. The MODEC signal on line 141 switches shift register 316 so that the AND element 318 is actuated to transmit the measurement information from data bus 13 into binary decoder 240 will. The output of the binary decoder 240 is then passed into the measure register 160 where it is stored.

As shown in Fig. 7, the AUTO signal is on Line 283 is an input to OR gate 178 and generates the SMPLA (secondary playback mode) signal on line 179 to AND gate 182. This signal is passed through the AND gate thanks to the signal SMINTR (not secondary interrupt mode) on line 187, which is derived from NOR gate 186. At this time all inputs are to the NOR gate 186 to logic 0, as will be explained later. The output of AND gate 182 allows the logic circuit to be sequential to read the characters stored in the circular memory 4, the Step value for ~ printing the line based on the accumulate read characters and edit the text. The characters are read by the shift register control and the decoding circuit shown in Fig. 2 and described above. The signal ACT.REQU. on the Line 57 also passes through inverter 172 where it is inverted and then input to AND gate 174 to generate the

909837/0643

AT9-77-007

To block print trigger block 14 and thereby prevent printing of the characters in the active query mode.

The text processing controller 190 shown in Fig. 8 operates because the signals SMPLA on lines 179 and SMINTR on line 187 to AND gate 182 are both at logic 1 and a switch-on signal on line 143 produce. The text handling control contains a counter to add the step values for the characters read from the memory. The remaining monitor 192 is at this time also active because of the output of the AND element 182. The remaining monitoring contains a comparator for comparison of the steps added in the text processing controller 190 with the total step set for the print line and for generation an output on line 193 when an overflow occurs and an output on the line 195 when the remainder, i.e. the step value remaining on the print line, becomes negative. Text editing control details 190 and the residual monitoring control 192 are well known and are described, for example, in U.S. Patent No. 3,991,405.

LINE OVERFLOW (WORD SEPARATION)

It is assumed that a word occurs during the text editing process which extends into the "hot zone". The term "hot zone" defines a variable remainder of switching steps immediately before a desired one extreme right margin. When the last word of a line ends within this "hot zone", the spacing between words within the line is acceptable Enlarged borders to get a balanced text margin. More detailed explanations can be found in the US patent No. 3,998,311. If a word occurs that extends into the "hot zone", the remainder of the monitoring function gives on line 193 the overflow signal UEBERL. According to illustration 9 routes the ACT.REQUIRED signal on the line

909837/0843

ÄT9-77-007

57 the OVERLOW signal on the line 193 through the AND gate 244 to set the overflow switch 248 and the switch 246. By setting the overflow switch 248, a signal is given to the controller 250 so that the system locate the beginning of the overflow word in memory. In the exemplary embodiment, this takes place in that the operating point in the circulating shift register is at the beginning of the overflow word is reset by taking the operation flag out of circulation in memory and at the beginning of the overflow word, as described above in connection with FIG. 2, starts again. Such a procedure is generally known to those skilled in the art.

When the operating point has been reset to the beginning of the overflow word, a signal for the start of overflow is generated given on line 251 to the overflow switch 248 to be reset. It is now assumed that the system does not have any interruption on this print line of the playback-free Machining process had. FIG. 8 shows how the combination of the signal AKT.ABFR. on the line 57 with the signal REF.ZEILE on line 253 the signal UEBER.ANF. on line 251 through AND gate 224 and conduct OR gate 218 to the line numbering switch

220 to set. The REF.LINE signal on line 253 is at logical 1 because the line number for this print line has not yet been printed. This signal is coming from reference line switch 252 in Fig. 9. By setting switch 220, the LINE NO. on the line

221 is generated and the line numbering control 222 is also called. The line numbering control forces that Printer 2 to print the number of the line in which the interruption occurred. The line numbering controller 222 contains a counter to add the number of lines of text that have been edited in playback-free mode. This type of line number processing is well known.

REFERENCE PRINT

As can be seen from Fig. 6, the LINE NO. Signal is present. on line 221 at a logic one level and runs through the OR gate 70, where it receives from the signal AKT.ABFR. passed on line 57 through AND gate 72 is used to generate a signal REF.PRINT IN on line 46. The signal REF.PRINT IN runs through the OR gate 36 and generates the signal AKT.ABFR. OFF on line 53 which in turn resets active interrogation interlock 1Q2 and a signal ACT. is generated at the logical ones level on line 77. The signal REF PRINT ON on the Line 46 also sets the reference pressure switch 100 and generates the signal REF.PRINT on line 115 with the logical ones level.

When the line number has been printed, the line number controller 222 turns the line number switch 220 through returns a signal on line 223, causing the LINE NO. signal to drop. on line 221 to logic 0. That Signal SMINTR drops out, i.e. SMINTR on line 187 becomes logical 1, and the active interrogation is deferred there and generated a logic 1 at the output of inverter 172, the AND gate 174 sends a signal to switch on of the pressure release block 14 is generated. The overflow word is now removed from the memory by the memory controller shown in FIG and decoding read and its characters printed out. The signal UEBERL is generated at the overflow point. on the Line 193 in Fig. 8 again a logic one pulse. It is passed through the AND gate 230 thanks to the Combination of the signal REF.DRUCK on the line 115 and the signal HYPMOD on the line 247, given previously became. The output of AND gate 230 passes through the OR gate 234 and turns on the control switch 236. This sends a signal on line 237 to the pressure controller 700 "PRINT M-" so that the printer circuit 7 is caused to print an "M-" and so the point in the

Word is designated at which the line overflow occurs. Simultaneously with the printing of M- the signal PRMDSH on the line 237 controls the output of the NOR gate 186, the signal SMINTR on the line 187 goes to logic 0. This means that the reading of the characters from the memory at the Control 184 by dropping the input to the AND gate and also printing the characters by the print trigger block 14 blocked because the AND gate 174 is blocked. When the M- character has finished printing, switch 236 is reset and the PRMDSH signal on line 237 goes to a logic 0 so that the SMINTR signal is on line returns to logic 1 and the AND gate 182 switches so that further characters from the memory by the controller 184 can be read. The AND element 174 is switched in such a way that the printing of the characters read in block 14 is also triggered will. This allows the rest of the overflow word to be reproduced or be printed out.

When the end of the overflow word is reached, the character decoder 56 decodes and generates a WORDEND signal a logical ones signal on line 48. Playback of the remainder of the overflow word produces a residual signal RESNEG on line 195 from residual monitor 192 in FIG. 8. If at AND gate 88 shown in FIG the residual signal RESNEG on line 195 and the signal HYPMOD on line 24 7 meet, the signal WORDEND passed on line 48 through OR gate 9 0. This signal is actuated in conjunction with the REF.PRINT signal the gate on line 115 from reference pressure switch 100 and generates a signal REQUEST PAUSE ON on line 32, and this turns on the REQUEST PAUSE switch 104. The INQUIRY PAUSE ON signal on the line is also canceled by the OR gate 82 conducted and generates a reset signal on line 49 for the reference pressure switch 100. As shown in FIG. 10, the INQUIRY PAUSE ON signal on line 32 also passes through OR gate 282 to the automatic switch 284 and the AUTO signal on the

Line 283 to drop to logic 0. This is query pause mode reached.

INQUIRY BREAK OPERATION

In FIGS. Figures 6 and 7 are shown as in interrogation pause mode the signal on line 119 produces an output from OR gate 158 to the keyboard power-up control 16 to switch so that the operator can use the keyboard. The pressure release block 14 is still active because that CURRENT REQUEST signal on line 57 is at logic 0. At this point, the operator normally leaves the overflow word Print out character by character using the character / top key on the keyboard. When the sign / stop button on the keyboard 3 is pressed, the signal from the character decoder 56 becomes a logical ones signal on the Line 37 and a logic zero signal on line 65 are decoded. The codes generated in this way will be not put into the circular memory 4, because the signal KEY on the line 65 with each depression of the character / stop key goes to logic 0 and thereby switches off the memory use control 168. The KEY signal is a decoding for whether a pressed key is a control key or a character key, and it is only logical 0 if a control key is pressed. However, depressing the character / stop key removes a character from memory is read by the Schxeberegxster control and decoding circuit 6, as described above in connection with FIG became. This character follows the code of the character / stop key on the data bus and is used by printer 2 in response printed on a signal of the print trigger block 14, which was switched on after the signal KEY on the line 65 went to logic 1. When the operator presses a character key on the printer, this character is encoded and appears the data bus. At this point, however, the printing process is switched off because the KEY signal is on logical

909837/0643

AT9-77-007 - 22 -

0 is because the character is on the data bus from a Keyboard key originates. However, if the character / stop key is pressed during the query pause, a character will appear read from memory immediately after pressing the key. When the character read is on the data bus comes, the TASTE signal is now decoded as a logical 1, since the character that has been read is now being decoded. Hence the Print trigger block 14 switched on so that printer 2 prints the character as it appears on the data bus.

The operator continues to press the character / stop key one after the other, thus printing the characters of the word until a corresponding separation point has been reached. At this point, the operator keyed in a hyphen on the keyboard. The hyphen is inserted by the memory insert controller 168 on the basis of a signal from the AND gate 164 that by combining the signal ABFR.PAUSE on line 119, the signal SMPLA on line 181 and des Signal KEY on line 65 is generated. The signal SMPLA is a logic 1 because the output of the OR gate 178 is a logical 0 and the KEY signal on line 65 is a logical 1 because the key depressed is not one Control button was. The hyphen is also printed because the print trigger block 14 is still active. When the hyphen is keyed in, it is decoded by character decoder 56 into a signal on line 34 in FIG. This signal sets the switch 268 in Fig. 9 and, when the system is as described below, simultaneously with the signal CURRENT REQUEST ON on line 59 and the HYPMOD signal on line 247 returns to active interrogation Inserted a carriage return (WR) from switch 274 into memory after the hyphen. The WR ON signal on the line 273 also resets the HYPMOD switch 246 via the OR gate 24 2.

Once the correct separating point of the overflow word has been determined and the hyphen has been keyed in, that can

System can be returned to edit mode without playback by pressing the automatic button on the keyboard 3 presses .. If the signal for the interrogation pause on the line 79 in Fig. 6, a signal for working "not on of the last line "in the playback-free operating mode on the line 81 and a decoding of the automatic key on the Line 67 meet, the signal AKT.ABFR. A on the line 59 by the AND gate 64 and the OR gate 68 generated. With this signal, the switch 104 is via the Line 121 is reset by the OR gate 94 and the automatic switch 284 is set in FIG. 10 and the AUTO signal generated on line 283. The signal ACT.REQU. ON on line 59 also turns switch 102 on and on generates a logical one-signal AKT.ABFR. on line 57. At this point the system maps one more time logical ones signal for the secondary operating mode SMPLA by the AUTO signal on line 283 in FIG. 7 via the OR gate 178. Signal SMINTR on line 187 is also at logic 1, since all inputs to NOR gate 186 are on are logical 0. The system therefore further edits the text through the text editing controller 190 in Figs again holds back the rest and monitors the overflow conditions through the residual monitoring 192.

The operator also has the option of not separating the overflow word, but rather the entire word around a print line to put down. If it is decided that the word should be placed on the next print line, then just press the automatic button. As shown in FIG. 9, the ACT.ABFR. A on the Line 59 derived from the above description by depressing the automatic button. If between the overflow word and the preceding word has a single space, then the signal SINGSPA is on line 255 from the block 250 a logic 1. This signal switches simultaneously with the signal HYPMOD on the line 247 and the signal CURRENT REQUEST ON on line 59 to AND gate 276 den

909837/0643

AT9-77-007,.

Switch 278 on, which is used for the shift register control and decoding circuit 6 goes to replace the space with a carriage return in memory. The ERS.SCHR. on of line 259 also resets HYPMOD switch 246 via OR gate 242.

If there are several spaces in front of the overflow word, then the inverter 264 supplies a signal via the OR gate 270 to the AND gate 272, which in conjunction with the signal AKT.ABFR. EIN on line 59 and HYPMOD on line 747 sets switch 274 so that a carriage return is placed in memory before the overflow word. The signal WR ON on line 273 also resets HYPMOD switch 246 via OR gate 242. The system then works return to the active query as described above.

REFERENCE PRINT

In the following text processing, it is next assumed that the system has responded to an interrupt code which is decoded by the character decoder 56 to a logical ones signal on the line 69 shown in FIG will. This interrupt code can be a stop code, an error code, an output code, an operating mode / mass code Tab / index code or any other predefined code. When a signal is INTERRUPTED C occurs on line 69 shown in FIG. 8, simultaneously with the ACT.ABFR signal. on the line 57 through the AND gate 194, then the switch 200 is set via the OR gate 198 to the control

202 to find the last print mark. The controller 202 causes the above in connection with FIG described shift register control and decoding circuit to the operating point by one character per memory cycle reset until the character decoder 56 decodes a print character on line 39. If a print mark is in shift register control and decoding circuit 6 is found, a signal from controller 202 is on line

Generating a signal to the line fallback control 212. The line fallback control 212 allows the Operating point in the shift register memory 4 run back until a line end character is recognized by the character decoder 56 and a signal is given on line 19. The end-of-line character is either an ordinary carriage return, a requested carriage return or a zero index carriage return. If one of these characters is recognized, it generates line fallback Control 212 sends a signal on line 213 to reset switch 210 and the line number switch 220 to be set via the OR gate 218. This causes the LINE NO. brought to logic .1 on line 221 and the line number control 222 is called as described above. The LINE NO. Signal on line 221, see FIG. 7, causes the SMINTR signal on line 187 to drop to logic 0 through NOR element 186. Through this in turn, reading of characters from the memory at the AND gate 182 is blocked as long as the LINE NUMBER signal is on Logical 1 stands, and the printing of characters at the AND gate 174 is also blocked. The LINE NO. Signal on the line 221 sets the reference pressure switch 100 on the line 46 via the AND element 72 and the OR element 70 in FIG. 6. The REF.PRINT ON signal on line 46 also sets the UPPER REQUEST switch 102 on line 53 via the OR gate 36 back. When the line number controller 222 has finished printing the line number on printer 2, the Line 223 generates a signal for resetting the switch 220 and the signal LINE NO. on line 221 logical 0 dropped.

Since the system has been taken out of the active query mode, the signal on line 57, which is at logic 0, inverted by inverter 172 in FIG. The SMINTR signal _on line 187 is also at a logical 1, since LINE NO. has decreased to logic 0. The character read control 184 is enabled by the AUTO signal on the line

909837/0643

AT9-77-007 _{? 6}

switched on via the OR gate 178 and the signal SMINTR on the line 187 via the AND gate 182, since the line numbering process ended. Text characters are output from the memory and controlled by printer 2 printed by the print trigger block 14 until the interrupt code is reached again in memory. The break code on line 69 in Fig. 6 goes into OR gate 90, is triggered by the signal REF.PRINT on line 115 passed through the AND gate 92 and generates the signal ABFR.PAUSE EIN on the line 32. This signal represents the Switch 104 on and the reference pressure switch 100 back via the OR gate 82. The INQUIRY PAUSE ON signal on the line 32 also represents the AUTO switch as shown in FIG via the OR gate 282 back. As shown in Fig. 7, with the activated signal ABFR.PAUSE the The keyboard is switched on via the OR gate 158 and the memory module control via the AND gate 164. The print release block 14 is still switched on because the system is not running in active query mode. The character reading control was switched off, however, because the AUTO switch was reset and the switches for LINE and WORD not yet were discontinued. The signal SMPLA is therefore at a logic 0 and the character reading control 184 is switched off.

In the interrogation pause mode, full control of the word processing device is available available to the operator to handle the interruption. Access types are in the Form of return lines available, memory slots are available, a keyboard for input / output information to and from memory as well as for printing on paper is available. Codes can be erased in memory or characters from memory can be played back while the system is in pause mode. The operation however, may only put the operating point in front of it word by word in the memory, since a prefix via paragraphs or lines the Line count accuracy. Therefore, as shown in FIG. 11, the signal from is decoded

909837/0643

the paragraph feed key on line 23, the signal from the top of page key on line 25 or the signal from Line feed key on line 27 in pause mode for setting the operation lock switch 314 through the OR gate 302 and the AND gate 308 to execute the playbackless editing process to end. After processing the interruption in the way selected by the operator, this can be System can be brought back into the playless edit modes by pressing the AUTO key on the keyboard.

We now assume that the system has returned to playless edit mode and a line overflow condition occurs in the same line as the previous interruption. The earlier break in As shown in FIG. 9, this line has the LINE NUMBER signal the switch 252 is set on the line 221 and a signal REF LINE is generated. Since there is no line code on this Point has been processed, the REF LINE signal is still present, when the overflow occurs. After the system has set the company code to the beginning of the overflow word in Has reset the memory and the signal OVERL. ANF. on line 251 became logic 1, as above in the other case of the hyphen, transmit the signal AKT.ABFR. on line 57 and the signal REF LINE to AND gate 254 the signal UEBERL. ANF. on line 251 to set switch 256 and on line 257 to generate the signal PRSPA. The signal on line 257 turns on the clearance pressure control 701 so that the Printer 2 advances the carriage a number of spaces. The PRSPA signal on line 257 also leaves the signal SMINTR on line 187 in FIG. 7 fall to logic 0 and switches character reading control 184 and the print trigger block 14 from. 6 shows how the PRSPA signal on line 257 is routed to OR gate 70 and by the signal AKT.ABFR. on the line 57 to the AND gate 72, the signal REF.PRINT EIN on the line 46 to give. This signal represents the active query switch

90983.7 / 0643

102 via the OR gate 36 and sets the reference pressure switch 100 via the line 46. After the carriage has advanced the required number of spaces, a signal is returned to the gap pressure control 701 which resets switch 256 and causes the PRSPA signal on line 257 to drop to a logic 0.

At this point in time, the playback of the overflow word continues, just as it was above in connection with the The dividing line and the "M-" inserted at the overflow point has been described. After the operation as described above has decided on the hyphen, the system can be brought back into the active query by you press the automatic button as described above.

If the system operates in an operating mode in which a forced overflow of the print line occurs, the Operate a reference expression to indicate the forced overflow. This condition occurs with special consequences, like centering sequences, where the text is pushed onto a print line. In Fig. 8 it is shown how the combination of the residual signal RESNEG on line 195 and the signal AKT.ABFR. on line 4 7 actuate AND gate 196 to output the end-of-line signal on line 19 to set the switch and print out the line of text on which the forced overflow takes place as described above for the overflow with a hyphen.

LAST LINE

Referring now to Figure 8, assume that the system is for an interrupt code on the last line was interrupted in the query area and the reference pressure for this interruption is started. After printing the line number as described above for an interrupt code the signal for the last line is on line 211 from detector 208 for the last line

1. With the resetting of the line number switches 220 and the simultaneous occurrence of the signal L.ZEILE on the line 211, the switch 236 via the AND gate 226 and OR gate 234 set to direct printer controller 700 to print an "M-" immediately after the line number to cause. Then, as described above for an interrupt code, the reference print runs to the interrogation pause mode Further. If the operator tries after processing the interruption code, it returns to the active query mode return, the system is prevented from setting the active query switch in Fig. 6 because the Signal L.ZEILE on line 31 to AND gate 64 is at logic 0. In Fig. 10, however, it is shown that the occurring simultaneously with the AUTO key signal on line 6 7 Signal for the last line on line 211 via AND gate 286 from the interrogation pause signal on the line 119 and through the OR gate 290 to set the ROW switch 294 and a logical ones signal LINE on line 295 to generate. In Fig. 7 it is shown how the LINE signal to OR gate 178 the SMPLA signal on the line 179 and the character reading control 184 turns on via the AND gate 182, since the signal SMINTR on line 187 is at logic 1. Since the system is not in the active query mode, the signal is on the line 57 to logic 0 and the AND gate 174 causes the print trigger block 14 to output the remainder of the last line, until a line end code is recognized. When the line end code is recognized as shown in FIG. 10, the Cell switch 294 is reset and the LINE signal drops to logic 0.

Next, the case will be dealt with where the interrogation area is reached without an interrupt code occurs on the last line. Int Fig. 8 can be seen how the system is in active query mode when the detector for the last line 208 detects the last line and that Signal LZ.DET on line 209 becomes a logical 1.

This signal is from the active interrogation signal on the line 57 via the AND gate 204 and via the OR gate

to set switch 200 and call controller 202 to find the last print mark. The controller moves the operating point backward in memory until a print character is reached, and then line recourse is made Controller 212 performs a line fallback exactly as described above. After executing the Line fallback, the reset signal on line 213 resets switch 210 and switch 220 via the OR gate 218 to control line number control 222 to print the line number for the last line in the query area to call. After the line number has been printed, a signal is generated on line 223 to reset switch 220, and this signal is via the AND gate 226 from the signal L.ZEILE on the line 211 and via the OR gate directed to set the switch 236 and the .Dr ^ uck- ·: i> Call controller 700 to print an "M-" after the line number for the last line. The PRMDSH signal on the Line 237 drops the SMINTR signal on line 187 in Figure 7 to a logic 0 and prevents character reading control 184 and the print trigger block 14 operate at this time. After the "M-" has been printed, the control system sets the switch 236 back and lets the signal PRMDSH fall to logic 0. The renewed occurrence of the signal SMINTR on line 187 turns on character reading control 184 and print trigger block 14 to read the characters for the last Line to print out. These continue to be printed out until the LZ.DET signal is displayed again at the same time as the REF PRINT signal the line 115 in FIG. 6 occurs to the reference pressure switch 100 via the AND gate 24 and the OR gate 82 of line 49 to reset. By resetting the reference pressure switch 100, the system is taken out of the query mode taken out because no other switches are set at this time.

Up to this point in time, a text block is defined by the number of lines entered by the operator in the area input mode was defined, has been processed according to the formatting parameters effective for this text block. the The operator now has the option of entering a new set of formatting parameters and returning to the query mode to call. Then a new area number can be entered around the text block defined by the new line number to process. In this way a page of text can contain so many different number of lines of text processed as required for a specific setting task.
