You can code the following to allow any number of arguments: the compiler will
generate the pseudo variables for you. I'm doing this from memory as I don't
have access to a PL/I compiler right now so please verify.
Declare myFunc External('VSHPARR') Entry;
If you were to code this:
Declare myFunc External('VSHPARR') Entry( );
It would indicate there are no arguments for the function, say for returning
the value of some constant such as PI.
PS, I would not use "TUPLE" for a PL/I parameter list, although no doubt the
.NET and PYTHON people love it.
