Request level isolation

If VTAM® can isolate an error to a specific RPL-based request, that request is posted complete with (RTNCD,FDB2)=(X'10',X'0E'). However, if damage was done to a session while processing the request, the error is considered to be at the session level or task level and is handled as described in the following sections.

For non-communication macroinstructions processed under the VTAM task, certain errors might result only in a VTAM operator message; it might not be possible to post the request complete.
