RE: Programmatically determine number of parms in procedure prototype?

You can specify a constant numeric value that represents the maximum
number of parameters your procedure can receive, then within the code,
check against that value, so when you have to maintain the procedure in
the future, you only need change the constant, not every instance you
check the number of parameters.

Subject: Programmatically determine number of parms in procedure
prototype?

All,

When using OPTIONS(*NOPASS) in a procedure parameter definition, it is
necessary to use the BIF %PARMS to determine the number of parms that
were passed.

Is it possible to determine the maximum number of parameters for a
procedure prototype?  It would be great to be able to do something like:

IF %PARMS = <total number of parms> THEN ...

or

IF %PARMS = <total number of parms - x> THEN ...

At times, I have a parm at the bottom of the list that is optional;
adding more parms above it means that I need to go back through update
the code that uses that bottom-most parm.

Any thoughts?

Thanks,
-Sean
