BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to soft key display on a screen in a CRT display device for an NC device.

0002

2. Description of the Related Art Conventionally, soft key definitions have been displayed in one row on the screen of a CRT display device for an NC device.

0003

[Problem to be Solved by the Invention] In such conventional technology, when the screen configuration specified by a soft key is a tree structure, when a soft key of a lower function is pressed, the definition and display of the soft key are all changed to the lower function. The display of higher-level functions disappears because the keys change to function keys. For this reason, it has become difficult to determine which function has a higher rank among the current functions. Therefore, it is an object of the present invention to make it easier to understand the upper and lower positions of the display contents of soft keys on the screen of a CRT display device.

[Means for Solving the Problems] In order to solve the above problems, the definitions of soft keys are displayed in two rows, upper and lower. When a softkey is pressed, whether it is considered to be the upper row or the lower row is determined by
The up and down selection keys are used to select up and down to make a decision. The upper row is a higher-order function group, the lower row is a lower-order function group, and each screen is assigned to a lower-order function. Each screen belongs to some higher level function.

[0005]

[Operation] With the above means, the higher-level functions are displayed on the upper soft key display area, so it is easier to understand the positional relationship of the currently displayed screen in the full screen configuration. selection) becomes easier.
