The biggest difference between a program and a procedure is that a
program is a procedure, but is also a separately compiled object and is
loaded on demand. Whereas a procedure can be a separately compiled
object, but may also be included in the same source member.
Programs are called dynamically, and loaded into memory on demand.
Procedures are called using the bound call interface, which loads the
procedures about 100 times faster than a program call. Procedures are
loaded when the initial program that uses them is called.

The called program can test %parms just like a subprocedure can, so I
think
this works for procs and progs.

c     *entry        plist
c                   parm                    inCount

c                   if        %parms < 1
c                   eval      loopLimit = 1000
c                   else
c                   eval      loopLimit = inCount
c                   endif
