RE: Conditional Processing with NoPass Parameters

No, you would use OPTIONS(*NOPASS) but then use the %PARMS built-in function
to detect the number of parms passed to your subprocedure.

Subject: Conditional Processing with NoPass Parameters


I have a program where I'd like one of the parameters to be optional (to
maintain compatiblity with a prior version of the program).  This is the
current prototype of the new program:

D CalcDat         pr                  ExtPgm('CALCDAT')          
D  inpDat                       10                               
D  inpDatFmt                    10                               
D  inpDays                       4  0                            
D  outDat                       10                               
D  outDatFmt                    10                               

I'd like to make outDatFmt optional since the original didn't have that
parameter.  I believe this is done via the "Options(*NoPass)", correct?  If
so, I believe if I use *NoPass I can't change the value of outDatFmt like
this:
                                       
      If outDatFmt = *Blanks ;         
        outDatFmt = inpDatFmt ;        
      EndIf ;                          
                                       
So, my question is:  What would be the best way to accomplish the above
goals?  Something along the lines of a working variable for outDatFmt?  Are
there other ways of checking for the missing parameter than "If %Parms" ?
