Nope! It doesn't work like C. :( A null-value or null ptr isn't the same as no parameter to the RPG language. :( You'd actually have to call Proc2 with no parms if no parms were passed, something like this: if %parms >=1; Proc2( InArg1 ); else; Proc2(); endif; Otherwise Proc2() will always think it has a parm passed, that is %Parms always returns 1. As to OPTIONS(*OMIT)... What a nightmare!!! callP Proc1(*OMIT); ... Then later, in Proc1... If %Parms >=1; if %addr(InArg1) = *NULL; Proc2(); return; endif; endif; Proc2(InArg1); Oh, and don't forget all those semi-colons in free-format;;;;;;;;;;; -Cozzi -----Original Message----- From: rpg400-l-bounces@midrange.com [mailto:rpg400-l-bounces@midrange.com] On Behalf Of Steve Richter Sent: Wednesday, January 08, 2003 11:03 AM To: Chat. Rpg400-L Subject: passing along *NoPass arguments Proc1 receives an arg that is *NoPass: pProc1 b dProc1 pi d InArg1 n options(*NoPass) /free Proc2( InArg1 ) ; /end-free p e and passes it along to Proc2 which also defines the arg as *NoPass: pProc2 b dProc2 pi d InArg1 n options(*NoPass) /free if %parms >= 1 ; dsply 'Arg1 is passed' ; endif ; /end-free p e In practice, Proc2 always thinks it was passed an argument. Even when Proc1 is called without an arg value. Shouldnt passing a not passed *NoPass argument either signal an exception or pass along the *NoPass indicator? I was hoping that options(*NoPass:*Omit) was the answer. That a missing arg value would be passed as *Omit and passed downstream as *Omit also. But it does not work that way. Unless Proc1 is called as "Proc1( *Omit ) ;", Proc2 will think it was passed something.
