With input (Constant) paraamerters and output parameters (not constant) and error parameters (*OMIT) so they can be omitted from the list.

By returning a value, you are creating a function which by definition will always return “a value”. Not two values or three values.

However, the value can be a structure; and you can use the single structure to carry a set of subfields.
