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:
o an INVOKE Statement on an object reference that is not a universal object reference,
o a program-prototype format of the CALL Statement.
The conformance rules for parameters and returning items apply at runtime when an explicit reference is made to them from a general rule.
NOTE - Conformance rules for parameters and returning items are checked at runtime for:
o a universal object reference
o the on-overflow and on-exception formats of the CALL Statement
NOTE - Conformance rules for parameters and returning items are checked for an object-view at compile time. Additional conformance rules for the object referenced by the object view are given in the rules of object-view; these are checked at runtime.
