 VXT Fortran
 ===========
 
    `g77' supports certain constructs that have different meanings in
 VXT Fortran than they do in the GNU Fortran language.
 
    Generally, this manual uses the invented term VXT Fortran to refer
 VAX FORTRAN (circa v4).  That compiler offered many popular features,
 though not necessarily those that are specific to the VAX processor
 architecture, the VMS operating system, or Digital Equipment
 Corporation's Fortran product line.  (VAX and VMS probably are
 trademarks of Digital Equipment Corporation.)
 
    An extension offered by a Digital Fortran product that also is
 offered by several other Fortran products for different kinds of
 systems is probably going to be considered for inclusion in `g77'
 someday, and is considered a VXT Fortran feature.
 
    The `-fvxt' option generally specifies that, where the meaning of a
 construct is ambiguous (means one thing in GNU Fortran and another in
 VXT Fortran), the VXT Fortran meaning is to be assumed.
