Gil,
Yes UADS was a PDS and there were some unusual items in UAD that were
semi hidden.
One I remember stumbling into was CPU time that the user had
accumulated since the creation of the ID.
Very sneaky (IIRC) .

I remember distinctly that UID's were limited to 7 characters.
One of the reasons was that UADS had a directory of 8 characters and
the 8th character was reserved for UID's needing more space in UADS
so a character was reserved (shaky here but the 8th character was
either 0, 1 2 etc) to allow more space ...
UID was 7 characters.
The eighth was reserved for UADS as either 0 thru 8
I've heard further that while UADS is a very ordinary PDS, updates
are performed in place to reduce the need for compress. As a
consequence, an existing member can't be extended except by
allocating an extension member.
