The operation of the above-configured document editing apparatus according to the present embodiment will be described below with reference to the flowcharts of FIGS.

In FIG. 3, first, when the operator turns on the power of the apparatus, in step 31, the data area 12-1 in the RAM 12 is initialized. Next, in step 32, the CPU 10 reads the initial menu from the operation menu storage unit 12-5 in the RAM 12, writes it in the display RAM 19, and displays it on the CRT 20. When the operator looks at this initial menu, the keyboard 14
Alternatively, when a document process is selected using the mouse 15, the process proceeds to step 35, and a document menu is displayed on the CRT 20 in step 36 of FIG. CRT2
When a tab setting is selected from the document menu displayed at 0, the process proceeds to step 39.

The operation of the tab setting routine will be described below. In FIG. 5, first, in step 42,
A buffer for tab setting is set in a buffer area 12-6 in the RAM 12. This tab setting buffer is RAM
12 has the same capacity as the tab information storage unit 12-2. When the tab setting buffer is set, step 4
At 3 the initialization of this buffer is performed. As shown in FIG. 11, the tab information storage unit 12-2 stores information on the tab position as one-word data. When the data area is initialized in step 31, all the tab positions are set to 0.0 mm. (However, if the system is set to edit by points,
0.0p). Initialization of the buffer for tab setting,
This is performed by writing the tab information storage unit 12-2 to the buffer area. The access to the tab information in the tab information storage unit 12-2 and the buffer for tab setting is performed by setting the desired address (the desired tab number-1) in the head address of the storage unit and the buffer.
This is performed using the address to which is added. When the buffer setting and initialization are completed, in step 44, a dialog box for tab setting as shown in FIG. 12 is displayed on the CRT 20, and the operator views the dialog box and sets a tab to an arbitrary tab number. You can set the position. If there is an input of a tab position from the operator, step 4
At 6, the data of the specified tab number of the tab setting buffer is written in the input value, and at the same time, the data in the buffer is displayed in the dialog box displayed on the CRT 20.

Here, when the operator designates execution of tab setting, the process proceeds to step 50, and the contents of the tab setting buffer are stored as tab data in the tab information storage unit 12
In step 51, the tab setting dialog box is erased from the CRT 20, the tab setting process ends, and the process returns to step 36 to display the document menu.

Next, a process of actually performing tab processing using the set tabs will be described. In FIG. 4, the CRT 20
When tab processing is selected from the document menu displayed in (1), the processing shifts to the tab processing routine shown in FIG. In this tab processing routine, first, a tab display routine for displaying the position of a tab that has been set and its tab number on the CRT 20 is executed. Hereinafter, the tab display processing will be described with reference to the flowchart of FIG.

In FIG. 8, in steps 67 and 68, a tab number 1 corresponding to the process and the maximum value of the tab number are set in the buffer area 12-6, and in step 69, a tab position is displayed. Line information is RA
It is read from the tab position display line information storage unit 12-3 in M12 and stored in the buffer area 12-6. Hereinafter, the processing from step 70 to step 76 is repeated for all the set tabs.

In step 71, the CPU 10 selects one of the tab data stored in the tab information storage section 12-2.
The tab data corresponding to the tab number is referenced. If the tab data referred to by the processing in steps 72 and 73 is the same as the position of the already processed tab or is in an area not displayed on the CRT 20, the corresponding tab number is set to 1 in step 76. , And the process proceeds to Step 70. The referenced tab data is not the same as the position of the processed tab, and
In the case of the area displayed on the CRT 20, in steps 74 and 75, a broken line and a tab number are displayed at the corresponding tab position.

Hereinafter, the line drawing process in step 74 will be described with reference to the flowcharts of FIGS. 13, 14, and 9. FIGS. 13 and 14 are diagrams schematically showing the relationship between the image RAM 18 and the display RAM 19 when editing one page of an A4 size document. The area indicated by the dashed line is written into the display RAM 19, and the CRT 20
It is assumed that it is displayed in. However, in this embodiment,
Although the case of horizontal writing is shown, the case of vertical writing can be implemented by the same concept. In FIG. 13, X and Y are the distances from the left and top edges of the edited page in columns, H is the height of the columns,
W is the column width, Dx and Dy are the distances from the left and top edges of the edit page in the display area, Dw is the display area width, Dh is the display area height, and Tx is the tab position set in the column set. so,
X, Y, Dx, and Dy are represented in a coordinate system having the origin at the upper left corner of the edited page. X, Y, H, and W are format data, and Dx and Dy are display position data in the RAM 12. It is stored in the area 12-2. x, y1, y2
Are coordinates for tab position display in the display RAM 19.

First, at step 77, the coordinate x of the tab position in the display RAM 19 is x = (X + Tx)
-Determined by Dx.

Next, in step 78, it is determined whether the upper end of the column displaying the tab position is within the display area (step 8).
0) Whether or not (step 79), the coordinate y1 of the upper end point of the broken line indicating the tab position is calculated as y1 = Y-Dy in step 80 and y1 = 0 in step 79.

In step 81, depending on whether the lower end of the column is within the display area (step 82) or not (step 83), the coordinate y2 of the lower end point of the broken line indicating the tab position is obtained. In step 82, y2 = Y + H- Dy, y in step 83
It is calculated as 2 = Dh.

As described above, when the coordinates for drawing the broken line representing the tab position are represented by the coordinates in the display RAM 19, in step 84, the CPU 10
The image controller 21 is controlled by the graphic interface program 11-1 stored in the RAM 11, and the image controller 21
, A dashed line at the corresponding position of the exclusive OR (hereinafter, EX-OR)
Write).

Hereinafter, the tab number display processing in step 75 will be described with reference to the flowchart of FIG. First, in step 85, the CPU 10
The tab number display character information such as the typeface and character size set at the time of initialization is read from the tab number display character information storage unit 12-4 in M12, and the numeric character code of the corresponding tab number, or , Tab position display coordinates (x-character size, y
Along with 1), it is sent to the image controller 21. Then, in step 86, the image controller 21
Generates a blank character of the corresponding tab number in accordance with the display character information of the tab number.
As shown in the figure, (x-character size,
y1) is written using EX-OR at the position based on y1), and the tab number is C
Displayed on RT20.

As described above, when the display of all the set tabs is completed, the tab display routine is terminated by the condition determination in step 70. When the tab display routine ends, the process proceeds to step 54, where a dialog box for inputting a tab number as shown in FIG.
It is displayed at T20. The operator looks at the tab position and tab number displayed on the CRT 20 and inputs a desired tab number. In step 56, the tab code and tab number are stored in a text file in the RAM 12 as shown in FIG. The data is written to the editing text file stored in the area 12-7. When the above process is completed,
In step 57, the dialog box for inputting the tab number is deleted from the CRT 20, and in step 58, the tab display routine is executed again.

Here, the purpose of executing the tab display routine in step 58 will be described. In the tab display routine, as described above, the broken line indicating the tab position and the outline character indicating the tab number are displayed on the display RAM using the EX-OR.
19, the data is displayed on the CRT 20. However, as shown in FIG. 20, due to the nature of the exclusive OR, the same data is additionally written on the data overwritten by the exclusive OR. If the data is overwritten by the logical sum, it becomes the same as the original data. Therefore, in step 58, the tab display routine is executed again to delete the broken line indicating the tab position and the tab number displayed on the CRT 20. I can do it.

When the set tabs are used for the aligning process (in this case, the equalizing process), when the equalizing process is selected from the display of the document menu in step 36, the equalizing process is started in step 41. . FIG. 7 is a flowchart showing the processing in the equal allocation processing routine. In the dialog box shown in FIG. 18, two tab numbers are specified, and the text file contains the equal allocation code and the Since it is the same as the tab processing except that the specified two tab numbers are written,
Detailed description is omitted.

As described above, in the present embodiment, when performing tab processing or alignment processing, the operator does not mistakenly designate the tab position because the preset tab position and the tab number are displayed. .

Further, since the tab number is assigned to the uppermost position of the broken line representing the tab position, the display of the tab number overlaps with the document being edited, so that it is not difficult for the operator to see the tab number. Furthermore, in this embodiment, the erasure of the tab position and the tab number is performed by overwriting using exclusive OR, so that the processing speed is improved.

In this embodiment, the tab positions are indicated by broken lines, and the tab numbers are indicated by white numerals. However, the tab positions are indicated by other line types such as solid lines. Anything that the operator can recognize may be used.
Also, the display of the tab number is not limited to a number as long as the displayed tab position can be designated.
