RETURN-CODE
is a computational (that is, binary) field that indicates the success or failure of the
operation requested. The return condition of RC-OK indicates success. The
possible error responses are explained below. A full discussion of the error codes
is in Appendix A of the SNAX/HLS Diagnosis and Support Manual..
SYSTEM-ERROR-CODE
is a modifier to RETURN-CODE:
If RETURN-CODE specifies RC-SYNTAX-ERROR, this identifies the field in error
by counting each field following the header fields.
If RETURN-CODE contains either RC-SEND-CHECK or RC-REQUEST-REJECT,
this field contains the first two bytes of the SNA sense data. The next two are
in the USER-ERROR-CODE field.
If RETURN-CODE contains RC-FILE-ERROR, this field contains the file error
code. This occurs only when opening a session.
If RETURN-CODE contains any value other than those listed above, this field is
undefined and should not be analyzed.
USER-ERROR-CODE
is an extension of the above error code. It is presently used to hold only the third
and fourth bytes of the SNA sense data.
RETRY-ACTION-CODE
is the summary indicator that indicates whether an unsuccessful request should be
retried. The value returned here can be installation-defined.
