RE: Ignoring a RETURN'ed value

["Bob Cozzi" <cozzi@xxxxxxxxx>]

Nope. The return value is thrown away if you ignore it by using CALLP.

Subject: Ignoring a RETURN'ed value

   I have a frequently-used pop-up which currently has two parameters: one
   input, the second output.
    
   I'm going to refactor the program to RETURN the value.  But I don't want
   to change the thousands of places it's used in hundreds of programs.
Yes,
   I could write a new program, but I donwanna.
    
   My plan is to add a return value to the protoype, RETURN the value,
   and handle parameter 2 as *NOPASS: if it's there, I'll return a value in
   parameter 2; otherwise I'll ignore it. 
    
   The question: if I have a return field specified in the prototype but do
a
   CALLP  {program}(parm1: parm2) instead of doing EVAL {result} =
   {program}(parm1), will there be h^ll (with a nod to the SMEX luddites) to
   pay?
    
   thanks,
   IRG
