(2) When the microprocessor unit 11 recognizes that a window display item has been selected from the screen editing menu and one window has been selected from the subsequent menu based on the value of the cursor pointer 12, the mouse switch-on operation, etc. , the window width signal generation circuit 17, the priority circuit 18, and the offset memory 19, respectively, to convert the specified window to the CRT display 1.
Display output on 3. That is, window width signal generation circuit 1
7 is a CR under the control of microprocessor unit 11.
;r Outputs a window width signal at the display timing of the window to be displayed in synchronization with the synchronization signal from the controller 15. This window width signal is input to the priority circuit 18. The priority circuit 18 determines the priority order based on the overlap of windows to be displayed under the control of the microprocessor unit 11, and selectively outputs the window width signal received from the window width signal generation circuit 17 according to the priority order. do.

The window width signal output from this priority circuit 18 is supplied to an offset memory 19. The offset memory 19 outputs the offset address of the window in synchronization with the window width signal received from the priority circuit 18. This offset address is input to an adder 20 together with the display address output from the CRT controller 15, and the offset address of the window to be displayed is added to the display address. The display address output from the adder 20 is given to the RAM 14 via the address selector 1B. This allows R.A.
The read address M14 switches from the main display area to the window display area every time the window to be displayed is displayed, and during that time, the data in the window display area is sent to the CRT display 13, including the window change menu. The specified window screen is displayed on the main screen. The display screen displayed on the CRT display 13 at this time is shown in FIG. 3(a), and its RAM
The data correspondence in 14 is shown in FIG. 4(a).

Here, when the [Size] area is specified by a mouse cursor movement operation in order to change the window size, for example, from the window change menu, the area specification is recognized by the microprocessor unit 11. When the microprocessor unit 11 recognizes this window size change designation, it displays the above [size] area in reverse display and displays the display data in the window frame display area around the window in the main display area of the RAM 14 in the same RA.
It is temporarily saved in a predetermined non-display area in M14, and frame data is written in that area. As a result, a window screen with a window frame (F) added is displayed on the CRT display 13. The display screen displayed on the CRT display 13 at this time is shown in FIG. 3(b), and the correspondence of data in the RAM 14 is shown in FIG. 4(b).

Next, by moving the cursor with the mouse, a command area within the window frame CF) is specified according to the content of the size change. That is, when changing the fixed size of the window, use the cursor to specify one of the areas rLJ, rDJ, rMJ, and "S" shown in FIG. 6 within area A3 of the window frame (F).

For example, by selecting rLJ, the maximum screen (horizontal 720
dots (45 characters) x vertical 920 dots (46 lines)), and by selecting rDJ, the default screen (horizontal 6
88 dots (43 characters) x 900 dots vertically (45 lines)), and by selecting rMJ, the intermediate screen (352 horizontal
dots (22 characters) x 460 dots vertically (23 lines)), and by selecting "S" the screen becomes the smallest screen (96 dots horizontally (6 characters) x 120 dots vertically (6 lines)).

Also, when resizing a part of the window, change the size of the area (L, D) within the window frame (F,).

Specify other areas (At to A8) except M, S) with the cursor. In other words, when changing the horizontal size, move the mouse cursor to area A within the window frame (F).
1. When specifying either A2 and changing the vertical size, perform the same operation as above to select area A3 within the same frame. A4
When changing the size in the vector direction by specifying either area A5. A8. Or A7. A: Specify one of 8. In FIGS. 3 and 4, either At or A2 is designated, the mouse switch is turned on, and the mouse is moved in that state. Since we are changing the size horizontally, move the mouse horizontally. The operating direction at this time does not need to be directly horizontal, but may be an oblique direction (vector direction).

The microprocessor 11 sequentially reads signals associated with mouse switch operations and cursor movement, recognizes the specified direction of the window size and the amount of change thereof, and controls the output signal width of the window width signal generation circuit 17 each time. , variably controls the window area according to the amount of mouse movement. As a result, the horizontal size of the window displayed on the display screen of the CRT display 13 changes as the mouse moves. The display screen displayed on the CRT display 13 at this time is shown in FIG.
The data correspondence within 4 is shown in FIG. 4(C).

Then, when the mouse reaches a predetermined window size, the mouse is turned off and turned off, so that the microprocessor 11 recognizes this state. The microprocessor 11 recognizes that the window resizing operation has been completed by switching off the mouse.

After that, by moving the mouse cursor to select the above [Size] area again and turning on the mouse, the display of the window frame (F) is canceled and the window frame (F) on the display screen is , read out the saved data of that part and return it to the main screen display, and display the resized window on the display screen together with the window change menu shown in FIG. 3(a) above; Set the display mode to allow the window to be changed again.

The above has been described using the example of changing the horizontal size of the window. For example, when changing the size to the upper left or lower right on the display screen, area A of the window frame (F) 5. A [i
All you have to do is specify with the cursor and move the mouse in the above vector direction. Also, when changing the size to the upper right or lower left on the display screen, move the area A of the window frame (F).
7. All you have to do is specify A8 with the cursor and move the mouse in the above vector direction.Also, when changing the size in the vertical direction on the display screen, move the area A of the window frame (F)
3. All you have to do is specify A4 with the cursor and move the mouse up and down.

Also, when moving the window in any direction, select the [Move] area from the window change menu above,
All you have to do is operate the mouse in the same way as when changing the size above. That is, for example, when moving the window in the horizontal direction, area A of the window frame (F) 1. All you have to do is specify A 2 with the cursor and move the mouse left and right. Also, to move the window up and down, click the window frame (F)
Area A 3. All you have to do is specify A4 with the cursor and move the mouse up or down.Also, if you want to move the window to the upper left or lower right, use area A of the window frame (F).
5. All you have to do is specify A6 with the cursor and operate the mouse in the above vector direction.Also, when moving the window to the upper right or lower left direction, move the area A7 of the window frame (F).
．． All you have to do is specify A8 with the cursor and move the mouse in the direction of the vector.

When the window screen is moved, the offset value of the window to be displayed in the offset memory 19 is rewritten under the control of the microprocessor unit 11 as the mouse is moved. Since these operations and processing means are easily understood from the above-mentioned size change processing operation, the explanation of the operation will be omitted here.

To scroll the window screen in any direction, select the [Scroll] area from the window change menu by moving the mouse cursor, and then click the window frame (F ), and then turn on the mouse switch each time you scroll. That is, for example, when sequentially scrolling the window screen in the horizontal direction, the area Bl, B2 or B3°B of the window frame (F) shown in FIG.
4 with the cursor and turn on the mouse switch each time you scroll. Also, when scrolling the window screen sequentially in the vertical direction, select area B5 of the window frame (F). B6 or B7. Specify any one area of B8 with the cursor and operate the mouse switch sequentially each time you scroll. Also, when switching the window screen to the previous page sequentially, press area B9 of the window frame (F) or BIO
After specifying with the cursor, turn on the mouse switch each time the page is changed, and when switching the window screen to the next page in sequence, press area B11 or B1 of the window frame (F).
2 with the cursor, and then turn on the mouse switch each time the page is changed.

Also, by selecting the "scroll" area again from the window change menu and turning on the mouse switch, the window frame (F) shown in FIG. 6 is erased.

As described above, by specifying the window change menu and the window frame (F) on the display screen using the mouse, various window change operations can be performed easily and quickly.

In the above embodiment, the window is surrounded by a window frame (F), and commands are divided into areas within that frame. A display form including a command designation area may also be used.

Further, in the above embodiment, menu selection and item selection are all performed using a mouse, but the invention is not limited to this, and other input means may be used.
