Calling sub programs

[Han]

It would help if you could explain what args are needed for the CAS function. If you are doing multiple arguments, then the non-CAS function must be defined explicitly in terms of those multiple arguments. I.e. the non-CAS program does not treat multiple arguments as a single "list" like CAS programs unless you literally pass a list of arguments to the non-CAS program in the form {arg1, arg2, ..., argn}
