I'm doing some RPG programs' development and I found that some of
these RPG require more input parameters from their caller (e.g. a CL
program), I feel confuse that they still working even the number of
the parameters are not match, for example, RPG A has 5 input
parameter and its caller CL B only gives it 3.

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.
