(2) Action The microprocessor unit 11 confirms that a window display item has been selected from the screen editing menu and one window has been selected from the following menus by the value of the cursor pointer 12 and the switch-on operation of the mouse. When it is recognized, the window width signal generation circuit 17, the priority circuit 18, and the offset memory 19 are controlled respectively, and the designated window is displayed on the CRT display 1.
Display output to 3. That is, the window width signal generation circuit 1
7 is CR under the control of the microprocessor unit 11.
The window width signal is output at the display timing of the window to be displayed in synchronization with the synchronization signal from the T controller 15. This window width signal is input to the priority circuit 18. The priority circuit 18 determines the priority order of overlapping windows to be displayed under the control of the microprocessor unit 11,
The window width signal received from the window width signal generation circuit 17 is selectively output according to the priority order. The window width signal output from the priority circuit 18 is supplied to the 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 the adder 20 together with the display address output from the CRT controller 15, and the offset address of the display target window is added to the display address. The display address output from the adder 20 is given to the RAM 14 via the address selector 16. As a result, the read address of the RAM 14 is switched from the main display area to the window display area each time the display timing of the window to be displayed is reached, and during that time, the data in the window display area is CR.
It is sent to the T display 13 and the designated window screen in the main screen including the window change menu is displayed. The display screen displayed on the CRT display 13 at this time is shown in FIG. 3A, and the data correspondence in the RAM 14 is shown in FIG. 4A.

Here, in order to change the window size, for example, from the window change menu, when the [Size] area is specified by the cursor movement operation of the mouse, the area specification is recognized by the microprocessor unit 11. When the microprocessor unit 11 recognizes the designation of changing the window size, the [Size] area is highlighted and the display data of the window frame display area around the window in the main display area of the RAM 14 is stored in the RAM 14. The data is temporarily saved in a predetermined non-display area and the frame data is written in that area. This gives C
A window screen with a window frame (F) added is displayed on the RT display 13. The display screen displayed on the CRT display 13 at this time is shown in FIG. 3B, and the data correspondence in the RAM 14 is shown in FIG. 4B.

Next, by moving the cursor of the mouse,
The command area in the window frame (F) is designated according to the contents of the size change. That is, when the fixed size of the window is changed, any one of the areas "L", "D", "M" and "S" shown in FIG. 6 in the area A3 of the window frame (F) is designated by the cursor. To do. For example, by selecting "L", the maximum screen (horizontal 720 dots (45 characters) x vertical 920
It becomes a dot (46 lines), and by selecting "D", the default screen (horizontal 688 dots (43 characters) x vertical 90)
It becomes 0 dots (45 lines), and when "M" is selected, it becomes an intermediate screen (horizontal 352 dots (22 characters) x vertical 460 dots (23 lines)), and when "S" is selected, the minimum screen (horizontal screen) 96 dots (6 letters) x vertical 120 dots (6
Line)).

Further, when the size of a part of the window is changed, the area (L, D,
The area (A1 to A8) other than M and S) is designated by the cursor. That is, when the size in the horizontal direction is changed, the area A in the window frame (F) is moved by moving the cursor of the mouse.
1 or A2 is specified, and when changing the size in the vertical direction, one of areas A3 and A4 in the same frame is specified by the same operation as above, and when changing the size in the vector direction, the area A5 is specified. , A6, or A7, A8 is designated. In FIGS. 3 and 4, either A1 or A2 is designated, the mouse switch is turned on, and the mouse is moved in that state. Since the size is changed in the horizontal direction here, the mouse is moved in the horizontal direction. The operation direction at this time does not need to be right beside, and may be an oblique direction (vector direction).

The microprocessor 11 sequentially reads the signals associated with the switch operation of the mouse and the cursor movement, recognizes the designated direction of the window size and its change amount, and outputs the signal width of the window width signal generation circuit 17 each time. The window area is variably controlled according to the amount of movement of the mouse. This allows CRT display 1
The horizontal size of the window displayed on the display screen of No. 3 changes as the mouse moves. The display screen displayed on the CRT display 13 at this time is shown in FIG. 3 (c), and the data correspondence in the RAM 14 is shown in FIG. 4 (c).

When the mouse reaches the predetermined window size, the switch-on state of the mouse is released and the mouse is switched off so that the microprocessor 11 recognizes the state. The microprocessor 11 recognizes that the window size changing operation is completed by switching off the mouse. Then, by moving the cursor of the mouse, the [Size] area is selected again, and the switch of the mouse is turned on to cancel the display of the window frame (F), and the window frame (F) on the display screen. Is erased, the saved data of that portion is read out and returned to the main screen display, and the resized window is displayed on the display screen together with the window change menu shown in FIG. Set the display mode so that the window can be changed.

The above description has been made by taking an example of changing the horizontal size of the window. For example, when changing the size in the upper left or lower right direction on the display screen, the area A of the window frame (F) is displayed.
5 and A6 can be designated by the cursor and the mouse can be moved in the vector direction. Further, when the size is changed to the upper right or the lower left on the display screen, the window frame (F)
The areas A7 and A8 of FIG. 7 can be designated by the cursor and the mouse can be moved in the vector direction. Further, when the size is changed in the vertical direction on the display screen, the areas A3 and A4 of the window frame (F) And move the mouse up and down.

To move the window in any direction, select the [Move] area from the window change menu and then operate the mouse as in the case of the size change. That is, for example, when moving the window in the left-right direction, the areas A1 and A2 of the window frame (F) may be designated by the cursor and the mouse may be operated in the left-right direction.
Further, when moving the window in the vertical direction, the areas A3 and A4 of the window frame (F) can be designated by the cursor and the mouse can be operated in the vertical direction.
Alternatively, when moving in the lower right direction, the regions A5 and A6 of the window frame (F) can be designated by the cursor and the mouse can be operated in the vector direction. When moving the window in the upper right or lower left direction, Area A of window frame (F)
7 and A8 may be designated by the cursor and the mouse may be moved in the vector direction.

When moving the window screen,
As the mouse moves, the microprocessor unit 11
Under the control of, the offset value of the display target window in the offset memory 19 is rewritten. These operations,
Since the processing means and the processing means can be easily understood from the above-described size changing processing operation, the description of the operation will be omitted here.

When the window screen is scrolled in any direction, the mouse cursor movement operation selects the [Scroll] area from the window change menu,
The window frame (F) shown in FIG. 6 displayed on the display screen.
After selecting a desired scroll direction from, the mouse switch is sequentially turned on each time scrolling is performed. That is, for example, when the window screen is sequentially scrolled in the left-right direction, any one of the areas B1, B2 or B3, B4 of the window frame (F) shown in FIG. 6 is designated by the cursor and the mouse switch is scrolled. When the window screen is sequentially scrolled in the vertical direction, the mouse switch is scrolled by designating one of the areas B5, B6 or B7, B8 of the window frame (F) with the cursor. Operate sequentially one by one. Further, when sequentially switching the window screen to the previous page, after the area B9 or B10 of the window frame (F) is designated by the cursor, the mouse switch is sequentially turned on each time the page is switched, and the window screen is sequentially switched to the next page. Area B11 of window frame (F) when switching to page
Alternatively, after designating B12 with the cursor, the mouse switch may be sequentially turned on each time the page is switched. The window frame (F) shown in FIG. 6 is deleted by selecting the [Scroll] area again from the window change menu and turning on the switch of the mouse.

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

In the above embodiment, the window is surrounded by the window frame (F) and the command area is divided within the frame, but the invention is not limited to this. For example, each side of the window is divided. A display mode may be provided in which a command designation area is provided in part.
