Eight-character TSO Userid Support::
Application environments are responsible for supporting whatever the
current architected userid length is. It has been asserted that TSO
is the only z/OS application environment in 2011 (soon 2012) that
can't handle that fundamental requirement. I'm trying to discover if
that's a true statement. None of the responses I've received
thus-far have offered anything to disprove that assertion. If true,
fixing TSO will provide *complete* eight-character userid support
for z/OS.
The problem with allowing TSO to use 8 Character USERIDs is that it
makes some TSO commands fail. Jobnames are 8 characters max. Submit
(at least ISPF Automatic Submit) adds a one character suffix to the
UserID and thus breaks if the UserID is 8 Characters (since that
would result in an invalid length 9 character JOBNAME). Also OUTPUT
(used by ISPF 3.8) validates that the JOBNAME is UserID+1_Character
and thus would not be able to handle 8 character UserIDs.
