 Return instruction return [expression]; return is used to return control (and possibly a result) from a NetRexx program or method to the point of its invocation. The expression (if any) is evaluated, active control constructs are terminated (as though by a leave instruction), and the value of the expression is passed back to the caller. The result passed back to the caller is a string of type Rexx, unless a different type was specified using the returns keyword on the method instruction for the current method. In this case, the type of the value of the expression must match (or be convertible to, as by the rules for assignment) the type specified by the returns phrase. Within a method, the use of expressions on return must be consistent. That is, either all return instructions must specify a expression, or none may. If a returns phrase is given on the method instruction for the current method then all return instructions must specify an expression. |
