    February 1996

    This guide describes how to install Digital Fortran (formerly DEC
    Fortrantm) on a VAX processor running the OpenVMS operating
    system. It also describes how to read the online release notes.

    Revision/Update Information:  This revised guide supersedes all
                                  previous DEC Fortran installation
                                  guides for OpenVMS VAX Systems.

    Operating System:             OpenVMS VAX Version 5.4
                                  (or higher; see Section 1.1)

    Software Version:             Digital Fortran Version 6.4 (or higher)
