VALUE

The VALUE keyword indicates that the parameter is passed by value rather than by reference. Parameters can be passed by value when the procedure they are associated with are called using a procedure call.

The VALUE keyword cannot be specified for a parameter if its prototype was defined using the EXTPGM keyword. Calls to programs require that parameters be passed by reference.

The rules for what can be passed as a value parameter to a called procedure are the same as the rules for what can be assigned using the EVAL operation. The parameter received by the procedure corresponds to the left-hand side of the expression; the passed parameter corresponds to the right-hand side. See EVAL (Evaluate expression) for more information.
