If you look at SYS$UPDATE:LIBDECOMP.COM, you'll see that
procedure uses LIBRARY/DATA=EXPAND on each library that
meets its criteria.  The /DATA qualifier is undocumented,
or at least, not present in the HELP for LIBRARY.

However, using Joe Meadow's VERB utility, you find that
the /DATA qualifier takes one of two keywords, REDUCE
or EXPAND.

So you could go through and LIBRARY/DATA=REDUCE on all
your (big) libraries, if you're so inclined.  I've not
tried it, but I expect that if the compression is done
in-place, you'll need to truncate the library file
afterwards.  OTOH, the command may very well create
a new version of the library file, in which case you'll
need to PURGE those files afterwards to recover the
disk space.

But to your original problem, that the Multinet 
installation is HUGE, I seem to recall that you're
getting all the architectures in the one download
(at least that was the case the last time I looked
10 years ago).  If you do some BACKUP/LIST commands
on those savesets, I think it's pretty easy to figure
out which ones are for VAX versus Alpha, and by
extension, IA64.  Just delete the Alpha and IA64
savesets and you'll recover far more disk space than
compressing help libraries...
