The Question is: We are upgrading from v6.1 to v7.2 for Y2K. Will the Fortran programs currently running need to be recompiled for the new version of the OS? Current Fortran Licenses: FORTRAN DEC FORTRAN-HPO DEC FORTRAN-IV DEC FORTRAN90 DEC Also, is it possible to install 7.2 onto the following: Volume label Free blocks Free Space Total Space "AXPVMSSYS" 416292 213 MB 1.05GB Thank you. The Answer is :
There is generally no need to recompile or relink user-mode applications
when performing an OpenVMS upgrade -- OpenVMS is quite compatible across
software upgrades. That said, recompilation with newer compilers can
take advantage of improvements made to the compiler code generation, and
can load newer object code if the applications are linked against
OpenVMS object libraries. (Most applications should link against the
OpenVMS shareable images, very few should link against object libraries.)
Code that uses privileged-mode (executive or kernel) routines or data
structures may require changes and/or recompilation and relinking.
Please see the OpenVMS Alpha Upgrade and Installation documentation
for specific upgrade requirements -- from the experience of the OpenVMS
Wizard, the current 1.05 GB (RZ26?) system disk will be tight. The V7.2
upgrade manual is presently available at:
http://www.openvms.digital.com:8000/72final/6522/6522pro.html
The V7.2 upgrade will require a maximum of 360,000 blocks free on the
system disk, possibly less. Please see:

Please see the OpenVMS Frequently Asked Questions (FAQ) for pointers
to Y2K readiness information and to the application and system Y2K
testing procedures recommended by OpenVMS Engineering. (The OpenVMS
FAQ is accessable at the Ask The Wizard web page.)
The OpenVMS Wizard would also recommend the release notes and new
features manuals for V6.2 through V7.2, inclusive -- this will help
you avoid various known and documented restrictions, and to take best
advantage of new features and changes that have been made to OpenVMS.
ECO kits are based on PCSI starting with OpenVMS Alpha V7.1-2 and later.
Prior to this, VMSINSTAL ECO kits were used. Do not attempt to use
VMSINSTAL ECO kits on OpenVMS Alpha V7.1-2 or later.
