Re: Conditional Processing with NoPass Parameters

[Scott Mildenberger <scottmildenberger@xxxxxxxxx>]

Add options(*nopass) to the parameter defintion of outDatFmt. 
Having a working variable such as wOutDatFmt defined as
like(OutDatFmt).  Then use %parms to determine what OutDatFmt
should be and use wOutDatFmt anywhere else in the procedure.

       If %parms >= 5;         
         wOutDatFmt = OutDatFmt;
       else;
         wOutDatFmt = inpDatFmt ;        
       EndIf ;
