I have written a module 'DA' that shows where users are logged in.
But since it uses IUCVTRAP MODULE to get incoming messages (from PVM),
it doesn't work together with the famous program CHAT because
CHAT also traps messages himself. When I call DA in the CHAT-environment,
simply nothing happens as if the program were waiting for something.
No CPU time passes.

What must my module switch off or so to be compatible with CHAT?
I think it has to do with HNDINT or CMSIUCV.
Perhaps it is not very difficult to trap messages myself without
IUCVTRAP MODULE ?
