pass by reference
Method of passing data from actual parameters to formal parameters when the procedure is called. The method is defined in the parameter interface of a procedure. Pass by reference does not create a local data object for the actual parameter. Instead a reference to the actual parameter is passed to the procedure when it is called and the procedure works with the actual parameter itself. Input parameters passed by reference cannot be modified in the procedure. See also pass by value.
