CICS tutorial mentions maps and BMS. Is that the screen layout? Do I draw it or code it?

BMS map = screen definition (fields, positions, attributes). You code map source (or use a painter), assemble it, and the program SEND / RECEIVE MAP.
Symbolic map gives you COBOL field names in LINKAGE or WORKING-STORAGE depending on how you set it up.

When the map and the program disagree on field sizes, weird ASRA stuff happens. Keep them in sync.
