public class ByRef

extends VMSparam

Used to pass a parameter by reference. This is the equivalend to similar constructs in other languages, such as:

PL/I	declare efn fixed binary(31); sts$value = lib$get_ef(reference(efn));
BASIC	declare long efn call lib$get_ef(efn by ref)
C	int efn; lib$get_ef(&efn);

The following Java code performs the same operation:

 int efn;

 lib.lib$get_ef(new VMSparam[] {
                    new ByRef(efn)
                });
