SNAX/HLS Application Programming Manual

RECEIVECONTROL Verb

System Error
Is a computational qualifier for RETURN-CODE. This screen line displays the
SYSTEM-ERROR-CODE value of the verb reply—first in decimal, next in
hexadecimal, and followed by a standard label.
If RETURN-CODE is RC-SYNTAX-ERROR, the SYSTEM-ERROR-CODE indicates
the ordinal position of the parameter in error discounting the verb code and
session ID. If the verb causes an SNA negative response from the session
partner, the first two bytes of the negative response are returned here.
User Error
Is a computational qualifier for SYSTEM-ERROR-CODE. At present, this field is
used only for the last two bytes of negative SNA responses and LUSTAT
messages. The screen line displays the field first in decimal and next in
hexadecimal.
Retry Action
Indicates whether an unsuccessful request should be retried. The screen line
displays the decimal value for this indicator followed by text.
Recovery Tags
Are returned to allow the requester to correlate requests, responses, or replies.
BOM is the SNA sequence number of the first element of the data message and
EOM is the SNA sequence number of the last element of the data message.
RDQ
(RECEIVE-DATA-QUEUED-IND)
A value of Y indicates that more data is available for the user. RECEIVE-DATA
verbs complete immediately (with no internal queuing) until the indicator is N.
ESS
(ENTER-SEND-STATE-IND)
A value of Y indicates that the message bore the change-direction indicator. In
HDX-FF protocols, this indicates that you are expected to send data.
TIP
(TRANSACTION-IN-PROGRESS-IND)
A value of Y indicates that you are in bracket state (a unit of work). If the current
session PROFILE does not use brackets, the value is N.
