 Read Before Installing or Using VAX FORTRAN(tm) HPO Version 1.2

 AV-PC39D-TE

 Please take time to read the following information about the VAX FORTRAN
 High-Performance Option (HPO) product before installing the software.

 Installation Information

 This kit contains media and documentation for installing VAX FORTRAN
 HPO Version 1.2 on the VMS operating system.  The VAX FORTRAN HPO
 Installation Guide/Release Notes (included in this kit) explains how
 to install VAX FORTRAN HPO and provides a sample installation and IVP.

 Prerequisite Software

 VAX FORTRAN HPO Version 1.2 requires the following products:

 o  VMS Version 5.4 or higher; future maintenance releases may
    require higher versions

 o  VAX FORTRAN Version 5.6

 Digital also recommends using the VAX Language-Sensitive Editor (LSE)
 and VAX Performance and Coverage Analyzer (PCA) to optimize program
 performance.  Both LSE and PCA are available separately or in VAXset
 Version 9.0 or higher.

 If you have newly installed VMS Version 5.4 on your system and did not
 do an upgrade from a previous version of VMS, you should issue the
 following DCL command either before or after installing VAX FORTRAN
 HPO (the command requires the SYSPRV privilege):

    $ LIBRARY/SHARE/REPLACE SYS$LIBRARY:IMAGELIB SYS$LIBRARY:FORRTL,FORRTL2

 This command corrects a problem on newly installed VMS Version 5.4
 systems that causes the linker to issue informational messages about a
 "link date-time mismatch" between the FORTRAN Run-Time Library
 shareable images and the system shareable image library.  (The
 messages do not affect linking or running programs, and can be
 ignored.)  You need to issue the command only once and only on newly
 installed Version 5.4 systems.  The problem has been corrected in VMS
 Version 5.4-0A or higher.

 Release Notes Information

 Release notes for VAX FORTRAN HPO Version 1.2 are available on line as
 well as in the VAX FORTRAN HPO Installation Guide/Release Notes. To
 read the online release notes before installing VAX FORTRAN HPO,
 invoke VMSINSTAL and follow the instructions in the VAX FORTRAN HPO
 Installation Guide/Release Notes.  To locate the online release notes
 after installing VAX FORTRAN HPO, enter the following DCL command:

    $ HELP FORTRAN RELEASE_NOTES

 The release notes describe the new and changed features of VAX FORTRAN
 HPO Version 1.2, differences from previous versions, corrections, and
 other topics.  This information is of interest to system managers and
 application programmers.  Digital recommends that you read the release
 notes before using VAX FORTRAN HPO.

 o  Documentation

    The VAX FORTRAN documentation set comprises the following manuals:

       -  VAX FORTRAN Installation Guide (AA-H953G-TE)

       -  VAX FORTRAN Language Reference Manual (AA-D034E-TE)

       -  VAX FORTRAN User Manual (AA-D035E-TE)

    The VAX FORTRAN HPO documentation comprises the following manuals:

       -  VAX FORTRAN HPO Installation Guide/Release Notes (AA-PC38A-TE)

       -  VAX FORTRAN Performance Guide (AA-PB75A-TE)

    User documentation is always included for new customers.  For
    continuing customers, user documentation is included only if
    ordered separately or if the documentation has been revised.

 o  Software Product Description (SPD)

    The SPD provides an overview of VAX FORTRAN HPO and its features.

 o  SYS Support Addendum (SSA)

    The SSA describes the technical environment in which VAX FORTRAN
    HPO is supported.

 o  Software Performance Report (SPR)
