Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

─────REFERENCE Attribute────────────────────────────────────────────────────
 
     Forces an actual argument to be passed by reference. The formal
     argument receives the address of the actual argument rather than
     a copy of the actual argument. Any local change to the formal
     argument alters the value of the actual argument that called the
     routine.
 
     By default, all FORTRAN formal arguments are passed by reference.
 
     Restrictions: Applies to formal arguments only
