So, for psuedo-conversational programming (as it's called), you
simply keep all the important stuff in your own communication area (which
is in-memory) and this maintains state. Of course, you can also keep
(hidden) things on the screen (as you can on the IBM i) but in the 3270
world this takes up screen real estate. So, not recommended. But, you
can keep all screen-type information in a temp storage queue so that it is
available across screen interactions, too.

I just had a serious 40-year flashback to NEP-MRT programming on the
System/3 model 15D.  Get a session ID from the screen and use that to
restore all your session variables.

Here's a picture of one: https://urldefense.proofpoint.com/v2/url?u=http-3A__www.ibmsystem3.nl_stories_Jenny-5FC.html&d=DwIGaQ&c=usKnhNfiA3SpEGkR2TubeV6I5jE5rze8vzZE7OpWXXY&r=LD1savGZ6Gc4gIcG9yLPnyfe5Wy5IgPnRmF3qDwpJN4&m=ppXaucfJrjR0h3v28mpSOEwQXNnjwLScqZ6WCAvxmpc&s=ILqz0e-e16cpnpuepifZhZnyQFeAluQmyKqXA3GeG6o&e=.
