In the word processor 1 equipped with the electric circuit block as described above, according to the flowchart shown in FIG.
Line form setting processing is performed to set print formats such as tabs and margins. Hereinafter, the operation of this embodiment will be explained according to the flowchart of FIG. 4 and the screen display diagrams of the CRT 3 shown in FIGS. 5 and 6.

When setting the line form during memory editing work in the word processor 1, step S1 (hereinafter simply Sl
... S15), when the page key 2A is pressed, the host computer 13 fixes the text area screen 31 displayed on the CRT screen of the display unit 3 with $2, and sets the line form. Start the mode. When this line form setting mode is started, the text screen is fixed as described above, but the scale line 33 in the format area 32 is controlled so that it can be moved freely.

In S3, the host computer 13 starts 4-scanning, and when it determines that the left or right scale cursor movement key 2G (←) or 2-to-1 (→) has been pressed in S4, the data is stored in the RAM 19 as shown in S5. The pointer of the scale cursor 34 is moved in response to the pressing operation of the scale cursor movement key 2G or 2H.

In S6, the current cursor position memory 1 in the RAM 19
00 and the format area memory 102, it is determined whether the destination of the scale cursor 34 is a position substantially outside the CRT screen of the display unit 3, and it is determined that the destination of the scale cursor 34 is outside the screen. Then, the scale line 33 is horizontally scrolled, for example, by 20 rams (see FIG. 6), and the scale cursor 34 is controlled so that the destination is within the screen, and then the process moves to step 88.

On the other hand, if it is determined in S6 that the destination of the scale cursor 34 is within the screen, processing in S8 is performed. In S8, the scale cursor is moved on the CRT screen of the display section 3, and then the process returns to S3.

As a result of key scanning in S3, if it is determined in S4 that the scale cursor movement key 2G or 2 days is not pressed, it is determined in S9 whether each of the following set keys is pressed, If it is determined that there is a set key that has been pressed, then in the next step 810, a form corresponding to the operation of that set key is set, and then the process returns to 83. At this time S9
If it is determined that the left margin set key 2B has been pressed, the left margin 35 is set on the display section 3, and it is determined that the right margin set key 2G has been pressed. If so, the write margin 36 is set. still,
If the left margin 35 and right margin 36 have already been set, the previous margin is canceled and the latest one is stored in the RAM 15.19. If it is determined that the tab set key 2D has been pressed, the tab 37 is set, and if it is determined that the decimal tab key 2E has been pressed, the decimal tab 38 is set.

Furthermore, when it is determined that the hot zone set key 2F has been pressed, the hot zone is set, and when it is determined that the line space key 2I has been pressed, the line space is changed. Furthermore, if it is determined that the pitch key 2J has been pressed, the pitch is changed and the scale line is changed, and if it is determined that the tab clear key 2K has been pressed, the tab 37 at the cursor position is cleared, and the tab all clear key 2 is pressed. If it is determined that the button has been pressed, all tabs 37 and 38 are cleared.

Next, in S11, escape key (ESC key) 2
If it is determined that M has been pressed, all set line forms are canceled as shown in S12, the line form setting mode is canceled, and then the process moves to 316. In S13, after determining that the page key 2A was pressed again after being pressed in S1, 31
After registering the line form in step 4, the line form setting mode is canceled and the corresponding text is reformed in accordance with the registered line form in step 315. Then, in the next step 816, the scale cursor 3
4 is moved to the position of the scale line 33 corresponding to the three text cursors on the text screen 31, and the routine proceeds to the next routine. At this point, adjust the scale line 33 as necessary.
Alternatively, the text screen 31 is also horizontally scrolled.

(Effects of the Invention) As described above, according to the present invention, since the text screen is fixed even when the scale cursor is moved in the line form setting mode, the screen does not flicker for the word processor operator. This has the effect of reducing eye fatigue, and the shortening of the processing time of the internal circuit reduces the time required to save the next operation key, resulting in the effect of shortening the time required for memory editing work such as text.
