Similarly, when a signal indicating that the numeric key has been pressed is input, the numeric key signal TKE including the key input window identifier and the key code of the pressed key is output. Furthermore, when a part of the window is exposed and needs to be repainted due to the fact that a part hidden by another window appears, a new window is displayed, etc., the window identifier that needs to be repainted. And an exposure signal WEE composed of the exposure range within the window.

Further, the window control section 7 operates the window displayed on the display device 3 via the display control section 4 in the following manner in response to the input from the screen management section 8. When the window display request WSR is input, the specified window is displayed on the screen. When the window deletion request WER is input, the specified window is deleted from the screen. When the window drawing request WDR is input, it draws in the specified window according to the drawing data. However, the window display request WSR and the window movement request WMR are composed of a window identifier and a display position, the window deletion request WER is composed of a window identifier, and the window drawing request WDR is composed of a window identifier and drawing data.

7), (4) Function key F3: “Set”, (5) Function key F4: Only in the case of “Cancel” The window deletion request WER is output and the currently displayed data setting pop-up window is displayed. It is erased from above (step S208).

If the numeric key signal TKE is input in step S202, then step S204 is executed.
Similarly, the presence / absence of a pop-up window for data setting on the current screen is determined (step S209), the window drawing request WDR is output only when the pop-up window for data setting is displayed, and the input control unit is output. Based on the numerical value input from the input device 1 via 2, the result calculated by the control data calculation unit 9 is drawn in the data setting pop-up window (step S210).

In step S203, the exposure signal W
When EE is input, the window drawing request WDR
Is output to draw the inside of the window to be newly exposed (step S211).

In addition to the above operation, if necessary, a window display request WSR or a window deletion request WER is output to control the display or deletion of the window, or a window drawing request WDR is output to draw the inside of the window. I will let you.

If (5) function key F4: "Cancel" is pressed, the process ends without doing anything. (4) Function key F3: Only when "confirm" is pressed, it is judged whether the input flag is ON or OFF (step S316), and OFF.
If it is ON, the process ends as it is, and if it is ON, the temporary origin offset value and the temporary current value are set as new origin offset values and current values, respectively, and stored in the data storage device 52 (step S317), and the process ends.

In step S303, (3)
When it is determined that the signal indicates that the function key F3 "calculate" is pressed, the temporary calculation value, the temporary origin offset value, the temporary current value, and the input flag, which are variables used in the subsequent processing, are initialized. (Step S318).

A value obtained by multiplying the current temporary calculation value by 10 and the input numerical value is newly set as the temporary calculation value, and the temporary calculation value is set as the temporary current value.
A temporary origin offset value is obtained by subtracting the temporary current value from the current machine coordinate value stored in the data storage device 52 (step S320). Next, the input flag is turned ON (step S321), and the process returns to step S319 again.

On the other hand, if it is determined in step S319 that the numeric key has not been pressed, the above-mentioned step S319 is executed.
Similar to 308 and step S315, it is determined whether or not (4) function key F3: “confirm” or (5) function key F4: “cancel” is pressed (step S322), and other than the above input Returns to step S319. Also (5) function key F4:
If "Cancel" is pressed, the process ends without doing anything.
(4) Function key F3: Only when "confirm" is pressed, ON / OFF of the input flag is determined (step S323). If OFF, the process ends as it is, if ON, temporary origin offset value, temporary current value. Are set as new origin offset values and new values, respectively, are stored in the data storage device 52 (step S324), and the process is terminated.
