SEND-DATA Verb

The SEND-DATA verb sends data to the remote TP. The local TP moves data into the

SNAX/APC send buffer by using SEND-DATA. Using this verb does not necessarily

cause the data to be transmitted immediately. Subsequent SEND-DATA verbs cause the

new data to be concatenated with the data already in the send buffer. The data is sent to

the remote TP when the send buffer overflows or when SNAX/APC receives a verb from

the local TP that explicitly causes the data to be transmitted (flushes the send buffer).

These verbs are:

CONFIRM

DEALLOCATE

FLUSH

PREPARE-TO-RECEIVE

RECEIVE-AND-WAIT

When sync point support is employed, the SEND-DATA verb is used to send PS-

HEADERs.

SEND-DATA completes when SNAX/APC has placed the data in its internal send

buffer.

Note. The fields SD-DATA-LENGTH and SD-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.
