VMS Help CC, Messages, VOIDRETURN  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Message        The function "<name>" has return type void, and so
                must not contain a return statement with an
                expression.

 Description    The current function was declared with a void return
                type.  The expression specified in the return value
                will be evaluated but will not be returned to the
                caller.

 User Action    Either change the return type in the function
                declaration or remove the return value from the
                return statement.
