Example
procedure on_finish if getsig() != 0 dialog box "Signal received. signo = "+alltrim(str(getsig())) label "ON FINISH" elseif error() > 0 dialog box "Error received, error = "+alltrim(str(error())) label "ON FINISH" else dialog box "Successful exit" label "ON FINISH" endif return on finish do on_finish
