We have had support for user logs--that is, storing messages for each
user separately rather than in a SYS1.BRODCAST data set--for quite some
time. Does this problem exist with user logs? (I suspect not.)

Question: When you are reformatting the active Broadcast Dataset
(SYS1.BRODCAST) with the SYNC command, you create space for 100 global
Notices (the messages that everybody sees when they LOGON). How do you
change this number?
Answer: You probably would never want to change this number,
because 100 notices is adequate for most purposes. But what if you
really DO want to change this number? Then IBM tells you to zap a
fullword field at the beginning of TSO initiation module IKJEFXSR, and
re-IPL (maybe with CLPA, just to be safe). Again, you'd probably never
want to do this, because 100 notices is adequate for almost everyone.
Where is that number (100, or F'64') kept? It is actually a
fullword in the CVT itself, at displacement X'5A8'. It is not "chained
off the CVT". It is actually a fullword IN the CVT...!!!! Wow!
So how would a fullword in the CVT be changed? Presumably only at
IPL time. That's why IBM's method of changing it is so cumbersome,
since (I think) IKJEFXSR, which starts up TSO, has to put that number
into the CVT.
