pass by value
Method of passing data from actual parameters to formal parameters when the procedure is called, which is defined in the parameter interface of a procedure. In pass by value, a local data object is created as a copy of the actual parameter. Output parameters and return values are initialized when the procedure is called. Input parameters and input/output parameters are passed the value of the actual parameter when they are called. Modified formal parameters are only passed to the actual parameter if the procedure has been concluded without errors, that is, whenever the last statement is reached or when they are exited via RETURN (or EXIT or CHECK). See also pass by reference.
