[HECnet] SMG bug correction for VAX V7.2 and others

[gerry77 at mail.com]

I think I've found a solution for the infamous SMG bug on releases for which
actually HP does not (still) provide a patch: I've discovered that the
official published patch for OpenVMS VAX V7.3 works apparently flawlessy even
on V7.2 and maybe also on older releases like V7.1 and so on.

Obviously it cannot be installed via VMSINSTAL because the kit does check for
the correct version and release, but it's always possibile to extract the new
SMGSHR.EXE file from the kit and put it in place. To be safe, I've copied it
to the specific portion of my system root (e.g. DKA0:[SYS0.SYSLIB]) instead of
the better common one, but I do not have a cluster and SYS$SHARE does point to
both locations, so I've achieved the same result. After that I've just typed
INSTALL REPLACE SYS$SHARE:SMGSHR.EXE/OPEN/HEADER/SHARED and that's it!

I've done the same for my OpenVMS Alpha V7.2 system by using the V7.3-2 patch,
but in that case a newer release is temporarily needed to extract SMGSHR.EXE
from the PCSI kit because it's in the new compressed form that's not supported
by V7.2 (I do not know when it was introduced, I used a V8.2 to extract).

In the next few days, if I'll see that everything works without any problems,
maybe I'll rename the original SMGSHR.EXE file and replace it with the new one
so to have just one of it and in the right place.

Hope this helps!
