I think MCH3601 works well if you document that you never intend to have *NULL as a valid value passed to a param.
For a bound call, it's not safe to rely on MCH3601 to detect unpassed
parameters. If there happens to be a pointer on the parameter stack from
some previous call, your procedure wouldn't get an error if it tried to
access the unpassed parameter. Testing %addr wouldn't be reliable either.
I think it's ok for a program call because (I assume, but don't know for
sure), that the ILE CL program-entry-procedure initializes all the
parameter pointers to either null or the address of the passed parameter
before it calls the procedure.
