As described in Software AG's fine manual, Control variable is a variable attached to a map field, and has bi-directional flow of information:
- When sending a variable to be displayed on a map, you can change its attributes dynamically by assigning AD=/CD= to that control variable (much like the .ATTR in ISPF Panel).
- When the map finishes to process, you can ask the MODIFIED question on that variable. This is much like the MDT attribute in CICS.

Use the search capabilities of Software AG's documentation, and look for CV, DY & Control Variable.
