count Number of messages
subtask Subtask name
cmd Command entered
Subtask subtask does not process the command issued from the workstation because there is a backlog of count messages waiting to be sent to the workstation.
The command cmd is discarded. Processing continues on the remaining messages in the subtask queue.
Wait until the existing backlog of messages is processed, then re-issue the command. Use the mainframe VP390 modiFy command SHOW TASK to view the number of messages in the Output Queue of the subtask.
