Value Label Meaning
0 IPC-OK SNAX/APC returns this code if REP-CODE contains either
ALL-UOWS-OK (0) or UOWS-WITH-ERROR (2).

VERSION-CODE
This code indicates that the value in the VERSION-CODE
field could not be recognized by SNAX/APC.
2 INVALID-
RESOURCE-ID

specified in the IPC. This might indicate that the TP
issued a verb (other than TP-READY) when there is no
conversation. See Table 2-2.
3SERVICE-
DENIED
SNAX/APC denied processing for the verb request.
See Table 2-2.

request. The HEADER-RETURN-CODE-DETAIL field
indicates the specific reason for the error. If this error code
is returned, UOWS-OUT indicates the UOW that failed,
and no verb reply is returned for any UOW. No verb
processing took place for any of the UOWs in the IPC
message.
See Table 2-2.

type, or the message length exceeded the maximum length
configured for the SNAX/APC system.
