RECEIVE-CONTROL-W
AIT Verb (SF8)
The RECEIVE-CONTROL-WAIT verb remains outstanding until a message is
available for the APS session. The format of the reply is the same as would have been
received had a RECEIVE-CONTROL verb request been issued with the same message
at the top of the receive queue for the APS session. If there is no message on the
receive-queue, the APS screen hangs until data is available. If this situation causes a
deadlock, use the HLSCOM QMSG command to send an interrupt message to the APS
application.
The RECEIVE-CONTROL-WAIT screen is the same as the RECEIVE-CONTROL
screen, except for the name of the request that appears in the Request: field.
The RECEIVE-CONTROL-WAIT request screen is the same as the
RECEIVE-CONTROL request screen.
The RECEIVE-CONTROL-WAIT reply screen is the same as the RECEIVE-CONTROL
reply screen except the return code of RC-NO-DATA-AVAILABLE is never returned
here.
