Send Data

The only verb used to send data is:

&APPC SEND_DATA

Data can be in the form of one or more NCL tokens, or it can be a Mapped Data Object, or MDO. Even where multiple tokens are identified on the send operation, they are packaged as a single unit of transmission, called a GDS variable, to the remote end where they will eventually become available from a single receive request.

There is no limit to the number of variables or MDOs, or total size of the GDS variable used for transmission.

Following a successful send data operation the conversation remains in send state. Otherwise the return code information should be examined for details on the send failure.
