Function Code 0—Queue a Message to the INTCMD Environment of an NCL Process

Function Code 0 queues a message to the INTCMD environment (response queue) of a nominated NCL process. Three additional parameters follow the function code:

parameter_2

Specifies the length of the message in fullword binary format.

Limits: 1 to 256

parameter_3

Specifies the message to queue.

parameter_4

Specifies the NCL ID of the NCL process in fullword binary format.

Limits: 1 to 99999

The process must have issued a request to the subsystem; otherwise, the message is discarded.

Important! If the message is discarded, the caller does not receive any indication.
