>I mean if I have a shortcut menu and I want one of the options to return a .t. is something happened successfully, can I do that?

Nor really "return", but you declare the variable before calling the menu (or use an object property to store the result value) and check it after the menu call.

* mymenu1.mpr
DEFINE POPUP shortcut SHORTCUT RELATIVE FROM MROW(),MCOL()
DEFINE BAR 1 OF shortcut PROMPT "Success"
DEFINE BAR 2 OF shortcut PROMPT "Bummer"
ON SELECTION BAR 1 OF shortcut myvariable = .t.
ON SELECTION BAR 2 OF shortcut myvariable =.f.

ACTIVATE POPUP shortcut

* Form.RightClick()
myvariable = .f.
do menu1.mpr
WAIT WINDOW IIF (!empty(myvariable),  "Success!", "Bummer...")
