   ^^^^^^^^^^^
This is a very bad idea.  We had a customer who did the same thing.  The
system would hang if too many people would log on using the same id.
Make sure they use  different ids.  Otherwise it seems that internal
system tables  are getting filled up.

Also, how much memory is in the system?  We figure that the base system
needs about 1 meg, and then we add 512k for each additional terminal.  It
seems to work.   As I understand RM/Cobol is a memory hog.
