When I've use CVTUSER I had a mod to the macro the assemble the correct 
contents. However, once you bring in software not under the control of IBM or 
your installation, all bets are off. BTDT,GTS.

Getting an external vendor to change its code to fit installation conventions 
is a lot more than very little work. IBM has provided better tools. Why not use 
them?

Yes, using CVTUSER sensibly for a whole organisation requires authorised
code to run at IPL time, which must allocate a USERVT in common storage and
point CVTUSER at that.

There will be other ways, but once that work is done, it is relatively
little work to use it for each product that needs an entry.

I was just wondering whether people still use it.
