Bar(), Menu(), Pad(), Popup(), Prompt()
These
functions tell you about your most recent menu choice. The first
four indicate which bar, menu, pad or popup you picked. PROMPT()
returns the text for the chosen item. POPUP() can also tell you
if a particular popup has been defined.

Usage
|
nChosenBar = BAR()
cChosenMenu = MENU()
cChosenPad = PAD()
cChosenPopup = POPUP()
lPopupExists = POPUP( PopupName )
cChosenPrompt = PROMPT()

The timing for retrieving these items can be tricky. Your
best bet is to pass them to the processing routine you set up
with ON SELECTION, so you're sure you get the right value. These
functions are set only when there are ON SELECTION commands for
the items in question. For an item with no action set or with
just an ON command, these functions don't change.For an
interesting exercise in what changes when, add some pads with ON
EXIT conditions at various levels to the system menu. Put the
five functions here in the Debug window and make some choices.
Watch when the various functions have values and when they're
empty. Putting WAIT WINDOWs in the ON EXIT conditions makes it
particularly easy to see what's going on. As FoxPro works its way
down to the chosen item, the status functions reflect the level
currently being processed.
