I think our machine had this group account a000
feature as well, but
my memories have already been proved suspect :-).
The A000 master account being the system library was true for all versions
of TSB (2000A, 2000B, 2000C, 2000C', 2000F, 2000F', 2000E, and 2000/Access).
However, each OTHER account that ended in 00 being a group library for that
range (ie, B100 being a group library for accounts B101 through B199, etc.)
was not in all versions of TSB. I know for sure it wasn't in 2000A, 2000B,
and 2000E. I know for sure that it was in 2000/Access. I am not sure at all
about 2000C, C', or 2000F, F'.
Also, at least in 2000/Access, there was an additional mechanism besides
GET-$xxx (system library), GET-*xxx (group library), and GET-xxx (local
catalog)... if correct capabilities were assigned, you could also do
GET-xxx.YZZZ (specify a . and then an account id) to access files in someone
elses account regardless of the group you were in. This last method I had
completely forgotten about, and references to it in the documentation seem a
bit hidden. But it is there. Someone on the list reminded me of this a while
back :)
