RETURN statement

The RETURN statement terminates execution of the subroutine or function procedure that contains the RETURN statement and returns control to the invoking procedure. Control is returned to the point immediately following the invocation reference.

The RETURN statement with an expression should not be used within a procedure with OPTIONS(MAIN).

A RETURN statement without an expression is not valid in a procedure with the RETURNS option. Conversely, a RETURN statement with an expression is not valid in a procedure without the RETURNS option.

A procedure with the RETURNS option must contains at least one RETURN statement (with an expression, of course).
