I haven't coded for CICS, but I've heard it was like the old
Burroughs mainframe coding - one program invocation would speak to
all 100 or 500 terminals, on a transaction basis. Stateless
transactions (like on the web) and you have to keep track of all
the user states yourself - you are talking to all of them on the
same program thread.

The 400 programming model is that the program is talking to one
terminal on a single thread, making the logic much simpler.
