Subject: [EXTERNAL] How many userids?

How many userids does a largish z/OS system have these days? Dozens?
Hundreds? Thousands?

 

I remember in the early 80s we had 20,000 userids defined on our VM systems at 
University of Waterloo, but that was long ago and far away in many, many ways 
(and included students, who of course we considered barely human).

 

Any rough numbers-even if reported as "A friend's system"-would be 
interesting/useful. Thanks.
