I need to return to know if a calling program failed. The current syntax is

DO pgmname with parm1 , parm2

I think I need

DO pgmname with parm1 , parm2 , parm3

where parm3 is going to be .F. if called program failed. I could the code something like

IF !parm3
    return  parm3
ENDIF

calling program already displays a message and uses the code

RETURN .F.

What I cannot remember is how to assign a value to parm3,

TIA
