Also, the CPU 11 has a display information copying device that controls the display output of the window to be copied to another new window.
The display information copying apparatus 21 is connected to a multi-window control table by a control signal output from the CPU 11.
By operating 22, window control information for copying the display output of an arbitrary window to a new window is output to the window display device 17.

Next, the display information copying apparatus 2 will be described with reference to FIGS.
1. The multi-window control table 22 will be specifically described. 2 (A) to 2 (D) are views showing a display state of a multi-window, and FIG. 2 (A) is an initial state in which a window A to be controlled is displayed. Here, if the display of the window A is designated to be recorded by an external operation such as the mouse 12, the display of the window A is copied to the window B after the window B is generated. Next, as shown in FIG. 2 (B), when the display of the window A is designated to be recorded again when the display of the window A changes to the window A ', the display of the window A' Copied. Thereafter, as shown in FIGS. 2C and 2D, window A ″,
In the recording operation of the window A, windows are sequentially generated in the same manner and the screen display is recorded. As described above, the display information copying apparatus 21 is capable of copying a screen to be controlled to a plurality of windows, and a multi-window control table operated by the display information copying apparatus 21.
22 is configured as shown in FIG.

FIG. 3 is a diagram showing the configuration of the multi-window control table 22. The state shown in FIG. 3 (A) is the initial state shown in FIG. 2 (A).
Is shown. As shown in FIG. 3A, the base window manages a control table of each window displayed on the CRT 20, and points to an active window (a window targeted for key input) on the CRT 20. Each window control table has the next window and the previous window as points in the order of superposition on the CRT 20, and stores a pointer to the base window. These pieces of information control the display superposition of the window generated when the display copy is designated. The window memory address and the window memory length indicate display information on the window memory. After the transition to the state shown in FIG. 2B, the window memory is stored in the window memory as shown in FIG. 3B. A new window B is reserved and the window memory of window A is copied (copied), and then window B is pointed to.

 Next, the operation of this embodiment will be described.

FIG. 4 is a flowchart showing window copy control, and is a flowchart for explaining the operation when the display information copying apparatus 21 receives a display information copy designation. In the figure, reference sign Sn (n = 1, 2,...) Indicates each step of the flow.

First, in step S1, when the display information is specified to be copied,
In step S2, a new window management table WIN-B is generated. Next, the "next window" of the window WIN-A designated to be copied in step S3 is set to WIN-B, and
The "next window" of -B is set to 0, the "previous window" of WIN-B is set to WIN-A, and the "base window" of WIN-B is set to "base window" of WIN-A. Next, in step S4, a window memory for WIN-B is newly secured, and the window memory of WIN-A is obtained from the "window memory length" of WIN-A, and the memory is transferred to the newly secured window memory. In addition, "window memory address" of WIN-B,
“Window memory length” sets a newly secured window memory. With the above processing, window B
The window management table for is completed. Steps
In S5, the window to be displayed is obtained from the "pointer to the first window" of the base window, and the flow advances to step S6 to determine whether there is a window to be displayed in step S6. When the display window ≠ 0, it is determined that there is a window to be displayed, and the process proceeds to step S7, where the display window =
If the value is 0, it is determined that there is no window to be displayed, and the process ends. In step S7, the display window obtained in step S6 is displayed, and in step S8, the display window is set to the "next window" in the window management table.
And returns to step S6 to determine whether the obtained display window exists. Finally, it is determined in step S6 that there is no window to be displayed, and the process ends.

According to the present invention, when a command to open a new window is issued while data whose display content changes is displayed in the first window, the first window is input when the command is input. Since the data of the content displayed in the window is copied and stored, and the data of the same content as the first window at the time of issuing the instruction is displayed in the second window generated separately from the first window, The content of the changing data at a certain point can be individually fixed and held, and the data can be easily confirmed.
