NAME macro
The key system definition options for defining an ISC session on the NAME macro are: COMPT, OUTPUT, EDIT, and ICOMPT.
COMPT= and ICOMPT= specify the output and input components respectively to be associated with the LTERM being defined. The system definition example uses components defined as COMPT=1 and COMPT=2.
OUTPUT= should not be used on an ISC session.
Recommendation: If you do not want translation of ISC output to the session,
specify ULC. If session output can be uppercase or lowercase data,
or binary data, use ULC.
