          Read Before Installing or Using HP Fortran Version 8.0 for
          OpenVMS Alpha Systems

          October 2005

          This letter explains the Version 8.0 release of HP Fortran for
          OpenVMS Alpha systems.

          Product Packaging Information

          HP Fortran Version 8.0 for OpenVMS Alpha Systems includes the HP
          Fortran compiler, the HP Fortran 77 compiler, and their shared
          components (such as the HP Fortran run-time library system and
          the FORSYSDEF.TLB library). The Compaq Extended Math Library
          (CXML) is an optional component.

          Both HP Fortran Version 8.0 compilers recognize the Product
          Authorization Key (PAK) for either HP Fortran or HP Fortran 77.
          For example, if you have an HP Fortran 77 PAK, you can begin
          using the HP Fortran compiler. If you install both compilers,
          the command names are:

          o  HP Fortran: the FORTRAN (or F90) command

          o  HP Fortran 77: the FORTRAN command with the /OLD_F77 quali-
             fier

          While HP Fortran 77 currently supports a very few legacy com-
          patibility features not yet supported by HP Fortran, HP Fortran
          supports nearly all HP Fortran 77 extensions. For more infor-
          mation, see the compatibility appendix in the HP Fortran for
          OpenVMS User Manual.

          Installation Information

          For installation information, see the HP Fortran for OpenVMS
          Alpha Systems Installation Guide in your kit.

          Release Notes

          The HP Fortran release notes contain a summary of new fea-
          tures, known problems, restrictions, incompatibilities, and
          installation-related instructions.

          To read the release notes before installing HP Fortran, follow
          the instructions in the HP Fortran for OpenVMS Alpha Systems
          Installation Guide.
