Conformance for Parameters and Returning Items

The conformance rules for parameters and returning items apply at compile time when an explicit reference is made to them from a syntax rule.

Note: Conformance rules for parameters and returning items are checked at compile time for:
  • An INVOKE statement on an object reference that is not a universal object reference,
  • A reference to a user-defined function,
  • A program-prototype format of the CALL statement.
