The Question is:
How do I tell exactly which version of VMS 7.1 I am running. F$getsyi tells me
7.1, but i need to know which sub-version. Or would f$getsyi return the full
version, if i was running a sub-version.
The Answer is :
Both SHOW SYSTEM and f$getsyi("VERSION") return the full version of
OpenVMS in use, whether it be V7.1, V7.1-1H1, V7.1-1H2, or V7.1-2.
$ x = f$getsyi("VERSION")
$ show symbol x
X = "V7.2-1 "
$ show system/noprocess
OpenVMS V7.2-1 on node ...
On OpenVMS Alpha, the command PRODUCT SHOW PRODUCT/FULL can be used to
display information on the installed products, both for products installed
with PCSI and via the VMSINSTAL history file VMSINSTAL.HISTORY. (The
PRODUCT SHOW PRODUCT command also works on OpenVMS VAX, but fewer OpenVMS
VAX products are installed using PCSI, and the VMSINSTAL.HISTORY file is
first available to OpenVMS VAX products installed on OpenVMS VAX V7.3
baselevels -- and as of this writing, V7.3 is in field test.)
