Description

The BAR() function returns the most recently selected bar number from an Xbase style pop-up menu. If the pop-up menu has been defined using the DEFINE BAR command, BAR() returns the bar number. If the pop-up prompts have been defined using the DEFINE POPUP command, BAR() returns the line number of the prompt, starting with number 1 as the first line within the pop-up screen area. The BAR() function will return 0 if there is no active or defined pop-up, or if the [ABANDON] key was pressed from within a pop-up menu. The command SET COMPATIBLE must be set to "dbase4" when using Xbase style menus.

Example

procedure action
do case
case bar() = 1
    do editfunc
case bar() = 2
    do deletefunc
case bar() = 3
    do addfunc
endcase
return
