Unless you're using prototyped calls (which is the recommended technique), there is no way for the compiler to enforce the correct number of parameters on a call.

As such, you can call a program with as many (or as few) parameters as you want.

You'll encounter an RNQ0222 error if you try to access a parameter that is unpassed within the called program.
