Turns the display of menu captions ON or OFF. This applies to
both the drop-down menu style and the ring menu style.
A menu caption is defined as a clause (caption = “text”) attached
to a menu item or subitem as shown in this example:
menuitem OptNext {label="Next"caption="Displays next record in the current search sequence"}
It is designed to give information to the user about the effect of
selecting the menu option.
If the ring menu style is being used,
then the caption is enclosed in quotes using the format:
*n ="NEXT","Displays next record in the current search sequence"
Captions are displayed on the bottom line of the window. If the bottom
of the window is not visible, the lowest visible line is used. A caption
occupies its entire row, temporarily obscuring anything else on that
row.
If sys.MenuCaption is ON, menu captions are displayed
automatically for the menu caption which has focus.
If sys.MenuCaption is OFF, then menu captions are not displayed.
