Saw DFHCOMMAREA in a CICS program. Is that how you pass data between transactions?

Classic way to pass a small blob of data on XCTL / LINK / RETURN TRANSID. Caller and callee must agree on the layout and length.
Channels and containers are the newer bigger-pipe option. You will still see COMMAREA everywhere in old code.
