This invention relates to a computational technique for editing alphanumeric information.

According to the main auth. W Qk2773 a device for editing alphanumeric information is known, comprising a first block of switching elements, the output of which is connected to the output of an AND block, the output is connected to the first input of the first comparison block, the second input of which is connected to the first output of a control block and the first input of the AND block , output - with the first input of the control unit, the second input of which is connected to the first output of the second block of switching elements, the first inputs of the first element And and the first pulse generator, the second output - with the display unit and the first input of the second comparison unit, the third input — with the second output of the second switching unit

elements and the second input of the second comparison unit; the fourth output — with the first input of the code converter, the first output of which is connected to the second input of the first element I, the third input of which is connected to the output of the second comparison unit, and the output is connected to the third input of the first pulse shaper; which is connected to the second output of the code converter, and the first output is connected to the first input of the OR element, the second input of which is connected to the output of the second element AND and the first input of the memory block, the output to the second input of the block And elements, the input of the generator of single pulses is connected to the third output of the second block of switching elements, the output to the second input of the memory block, the third input of which is connected to the second output of the first pulse shaper, the output to the first input of the second element And, the second input

connected to the output of the third comparator unit, the third input to the output of the second pulse shaper, the first input of which is connected to the output of the first comparison unit, the second input to the third output of the code converter, the fourth output of which is connected to the first input of the third comparison unit, the second input of which is connected with the third input of the control unit Ct.

The disadvantage of this device is low speed due to the need, when editing information, the producer-movement of a marker within a row with a sign of one column is not the signs of the next columns with the help or step-by-step movement of a marker (from the first block of switching elements or using sequential input (from the second block switching elements) row numbers and columns.

The purpose of the invention is to increase the speed of the device.

The goal is achieved by the fact that a second single pulse generator, a second memory block and a third element I are entered into the device, the first input of which is connected via the second memory block and the second single pulse generator to the first output of the second switching element block, the second input is connected to the output of the second the pulse driver and the first input of the second element I, the third input is connected to the first output of the code converter and the first input of the first pulse driver, and the output is connected to the second memory block and and element OR

As a result, in the device, a significant increase in speed is obtained by allowing the marker to move from any character of any table column to the first character of the next column by pressing the switching element of the second switching element block once.

Fig, 1 shows the block diagram of the device; in fig. 2 - an example of the type of displayed reformation.

The device comprises a display unit 1, a control unit 2, a second block 3 of switching elements, a first generator 4 of the same pulses, a second driver 5 and 885

pulses, third comparison unit 6, code converter 7, second element 8, first memory block 9, first driver 10 pulses,

the first element AND 11, the second unit 12 of the comparison, the element OR 13, the unit And k elements, the counter 15, the first block 16 of the switching elements, the first block 17 of the comparison, the second generator

18 single pulses, the second memory block 19, the third element I 20.

The device works as follows.

In order to automatically install a marker on a character located in a subgroup of characters (for example, inside a table column) included in a group of characters (for example, within a table row), the operator must sequentially enter from the second block 3 switching elements, first signs {signs of a group of characters (line number ), and then the sign designation of a subgroup of characters. (column number).

In this case, using the interaction of blocks from the first to the seventeenth, the marker will be placed on the corresponding row of the table, on the first character of the corresponding column. After that, the operator removes from the output of the second block 3 of the switching elements the signal for the automatic output of the marker, which arrives at the first inputs of the first driver 10 pulses and the first element 11.

Editing in the selected subgroup of characters, for example, the second character in the first column (FIG. 2), the operator, in order to move the marker directly to the first character of the next column, inputs the control signal to the input of the second generator 18 of single pulses from the fourth output of the second block of switching elements 3 from the output of which a single pulse goes to the first input of the second memory block 19. After receiving a single pulse, which is stored in the second memory block 19, the latter inputs from its output a control signal to the first input of the third element I 20, to the second input of which a control signal is received from the output of the second pulse driver 5.

This signal appears in the process of displaying information once in a frame at times when

The screen of the display unit 1 on one of the rows of the table begins to form a marker (when the control signal appears at the output of the first comparison block 17) and disappears before the display of the characters of the next line number (when the signal from the third output of the code converter 7 appears at the second the input of the second driver 5 pulses). Thus, at the second input of the element I 20, a control signal appears immediately after the occurrence of the comparison signal, i.e. the beginning of the formation of the marker on the screen of the display unit 1.

At the third input of the third element I 20, in the process of displaying information, a control signal arrives each time when on the screen of the display unit 1 characters are formed that have the code indication of the first characters in the subgroup (in the column) 1

Thus, if the first and second inputs of the third element AND 20 control signals, at the time of displaying the first character having a code feature in the column, next to the column in which the marker is displayed, the signal from the second output of the code converter 7 will arrive to the third input of the third element AND, which generates a control signal from its output to the third input of the element OR 13. Next, the signal from the output of the element OR 13 goes to one input of the block of elements AND It and records in the current code counter 15 This is a familiarity coming from the output of the control unit 2 to another input of the AND 1A element unit.

As a result, the marker will be placed on the familiar display of the first character with a code prism in the column next to the column in which the marker was displayed.

At the same time, from the output of the third element I, a signal is sent to the second input of the second memory block 19, which sets this block to its initial state.

To set the marker on the familiar display of the first character with a code feature in the next column, the operator must remove the control signal from the input of the second generator of 18 single pulses and reintroduce it. Then the marker displayed, for example, on any sign of the second column will move to the first sign with the code sign of the next third column, etc.
