Set when the dual screen mode is set (the data is "l") and the display screen is divided into two display screens.
) flag data of the screen mode flag F is stored. Further, the RAM 20 is provided with various types of memories, counters, pointers, etc. for temporarily storing the results of calculations performed by the CPU 16.

Next, a document processing control routine performed by the control device C of the word processor I and a part of the related display control routine will be described with reference to the flowchart of FIG. In addition, 5i (i=io, 11.12...
・) is each step.

This control starts when a new document creation process or an editing process for an already created document is selected from either the first keyboard 3 or the second keyboard 4, or here, the document creation process is selected. I will explain when it happens. When this control is started, the display screen is cleared and both pointers 24 and 2 are cleared.
5 stores the storage start address of the document data in the text memory 23, and both cursors 40 and 4° 1 are displayed at the initial position of the display screen (for example, the left end position of the first display line).

Key scanning is repeated alternately for each keyboard 3 and 4 at minute intervals (SIO-3ll), and when any key is operated on the second keyboard 4 (Sll: Y
es), the code data corresponding to the key is stored in the second key buffer 22, and the second pointer 25 is selected (activated) (Sl2 513), and if this code data is a character code, the second pointer 25 is 25 and also controls the text memory 23 based on this second pointer 25.
In the case of a function code, editing processing is performed while controlling the second pointer 25 (S14).

Next, based on the data of the first pointer 24, the pointer 26
Data is stored in the pointer 27 based on the data of the second pointer 25, and data is stored in the pointer 27 based on the data of the second pointer 25, and both cursors 40 are stored based on the data of both pointers 26 and 27.
・41 can be displayed simultaneously in single screen mode, and even now when in single screen mode (S15・316
:NO), the addresses determined based on the pointers 26 and 27 are stored in the first display start pointer 28 and the first display end pointer 29, respectively, and the document data is displayed based on these pointers 28 and 29. At the same time, the first cursor 4o is displayed at the display position based on the pointer 26, and the second cursor 41 is displayed at the display position based on the pointer 27 (S19), and the process returns to SIO.

On the other hand, when any key is operated on the first keyboard 3 (SIO: Yes), control is performed in the same way as when any key is operated on the second keyboard 4. That is, to explain briefly, the code data corresponding to the key is stored in the first key buffer 21, and the first pointer 24 is selected (
S20 521), storage processing or editing processing in the text memory 23 is executed based on this code data while controlling the first pointer 24 (S22), and both cursors 4
0.41 or when it can be displayed in single screen mode (
S15/S16: No), return to SIO via S19. For example, when inputting document data from the second keyboard 4 and editing the document data using the first keyboard 3, if both cursors 40 and 41 can be displayed simultaneously in single screen mode, the document data and both cursors 40 and 41 are displayed as shown in FIG.

By the way, as a result of input processing and editing processing corresponding to the code data being executed in S14 or S22, when the positions of both cursors 40 and 41 are so far away from each other that they cannot be displayed on a single screen, both cursors 40 and 41 are displayed simultaneously. Dual screen mode or set to
When this dual screen mode is set, if the current single screen mode is set (315: Yes, S23: N
o) The address determined based on the pointer 26 is stored in the first display start pointer 28 and the first display end pointer 29, respectively, and the address determined based on the pointer 26 is stored in the second display start pointer 30 and the second display end pointer 31, respectively. The addresses determined based on these points are stored (S24), the flag F is set (S25), and when the first pointer 24 is selected (S26: Yes), the document is stored based on these pointers 28 and 29. The data is displayed in the upper half of the display screen, and the first cursor 40 moves to pointer 2.
6 is displayed in the upper half display position (S27). Furthermore, when the second pointer 25 is selected (S2
6: No), the document data is displayed in the lower half of the display screen based on these pointers 30 and 31, and
The second cursor 41 is displayed at the lower display position based on the pointer 27 (S28). For example, as shown in FIG. 6, when the display position of the first cursor 40 and the display position of the second cursor 41 are separated by 14 display lines or more, the document data and pointer based on the pointers 28 and 29 are displayed in the upper half of the screen. A first cursor 40 is displayed at a display position based on 26, and a first cursor 41 is displayed at a display position based on the document data and pointer 27 on the lower half of the screen.

On the other hand, when the dual screen mode is set in steps 315 to S28, as a result of the input processing or editing processing corresponding to the code data being executed in S14 or S22, both cursors 40 and 41 can be displayed simultaneously in the single screen mode. Sometimes (S15: No, S16: Yes)
, both pointers 30 and 31 are cleared, and the first
The addresses determined based on the pointers 26 and 27 are stored in the display start pointer 28 and the first display end pointer 29, respectively (S17), and the flag F is reset (318)1. The process returns to S10 via S19.

As explained above, while the first keyboard 3 and the second keyboard 4 and the first pointer 24 and second pointer 25 corresponding to these keyboards 3 and 4 are provided, input from both keyboards 3 and 4 is supported. and pointer 24.2
5 is selected, the document data is stored in the text memory 23 or the document data in the text memory 23 is edited based on the selected pointers 24 and 25, and the document processing results and both cursors 40 and 40 are displayed. 41, the document processing equivalent to that of two machines can be performed at the same time, and the document processing work can be greatly speeded up.

In addition, in the document processing control, S15 to S19 and S
23 to S26 are partially changed, and the dual screen mode is set at the start of this control, so that the first keyboard 3 and the upper screen are always associated, and the second keyboard 4 and the lower screen are It may also be made to correspond to the half screen.

[Another example]

As shown in FIG. 7, the document processing control is performed in steps S15 to S1.
9 and S23 to S26 are partially changed, the text memory 23 is provided with a plurality of text areas for storing a plurality of document data, and the first keyboard 3 and the upper half of the display screen are changed. The second keyboard 4 and the lower half of the display screen may be associated with each other, and the dual screen mode may be always set, so that each of the keyboards 3 and 4 accesses separate document data.

That is, the code data input from the first keyboard 3 is stored or edited in a specified, for example, first text area in the text memory 23 based on the code data while controlling the first pointer 24 through S20. This is executed (S21/522), and the document processing result in the first text area and the first cursor 40 are displayed on the upper half of the screen (S27). Further, the code data inputted from the second keyboard 4 goes through S12 to control the second pointer 25, and then stores or edits the code data in a specified second text area in the text memory 23, for example, based on this code data. is executed (S13 and S14), and the document processing result in the second text area and the second cursor 41 are displayed on the lower half of the screen (S28).

As explained above, document data input from the first keyboard 3 or document data edited using the first keyboard 3 and the first cursor 4 corresponding to the first keyboard 3
0 is displayed on the upper display screen, while the document data input from the second keyboard 4 or the second keyboard 4 is displayed.
Since the document data that has been edited and the second cursor 41 corresponding to the second keyboard 4 are displayed on the display screen in the lower half, the document processing equivalent to that of two machines can be performed at the same time. It can greatly speed up document processing tasks.
