SEND-DATA Reply Screen Description
Return Code
Displays the value of the verb reply RETURN-CODE in decimal followed by text.
System Error
Is 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 text.
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 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, and 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 data is available for the user. RECEIVE-DATA verbs
with complete immediately (with no internal queuing) until the indicator is N.
ERS
(ENTER-RECEIVE-STATE-IND)
A value of Y indicates that the session partner wishes to send data and has sent an
ATTENTION request. The APS session is expected to set the PREPARE-TO-
RECEIVE indicator on a subsequent send verb when convenient.
