Issue: 

I need to know what the meanings are for the return codes on the ROS602I LOSTERM error message.

Environment:
IBM VTAM

Cause: 

Reason codes indicate an IBM VTAM error. Roscoe has to close the user session.

Resolution:

Here are the codes and their meanings:

12The session has been terminated. The operator may have deactivated the LU or the LU might have had an unrecoverable failure.
16The session has been terminated. This reason follows reason code 24.
20A CTERM Forced request has been received. Perhaps the LU issued a Terminate Forced request.
24The session has been terminated. The LOSTERM exit routine is immediately rescheduled with reason code 16 for this session.
32A CTERM Conditional request has been received. Perhaps the LU issued a Terminate Orderly request.
36Received request or response units for this session have been discarded because of a lack of buffer space.
44A cross-memory macroinstruction request failure has occurred.
48A CLEANUP RU has been received. VTAM will close the session.
