• Specify the message port number of the message port to be deleted in <message port

number>.

• In order to delete message ports, it is necessary to close all open message ports in all

programs being executed concurrently in multitask operations.

An error occurs if the ZMESSAGE KILL instruction is executed while there is still one or

more programs that have not closed all message ports.

Execute the deletion of the message ports by the ZMESSAGE KILL instruction in either one
of the programs being executed concurrently in multitask operations.
