RECEIVE-AND-WAIT Verb
RECEIVE-AND-WAIT Verb
The local TP issues RECEIVE-AND-WAIT when it is ready to receive data or control
information from the remote TP. The local TP can issue RECEIVE-AND-WAIT while
in Send state to flush the data buffer and cause a transition to Receive state. Successful
completion of the RECEIVE-AND-WAIT verb occurs when the local TP receives data
or information from the remote TP. The WHAT-RECEIVED indicator informs the local
TP of the type of information received.
Note. The fields RWR-DATA-LENGTH and RWR-DATA-AREA are not defined by the
SNAX/APC DDL because they cannot be created by DDL. The SNAX/APC DDL
provides example definitions for these fields in COBOL and TAL. You must create the
definitions for these fields.
