The ST (Stop) command temporarily suspends jobs or tasks. The jobs or tasks can be reactivated by the OK (Reactivate) command. This command sometimes has no effect on an MCP independent runner, but you can usually terminate such a task with the DS (Discontinue) command.
Syntax

Explanation
<mix number list> ST
Temporarily suspends the jobs or tasks in the mix number list.
Example
1024 ST
1024 OPERATOR STOPPED
Considerations for Use
You can use the OK (Reactivate) command to reactivate a task that you have stopped with either an ST or a CANDE ?ST command. CANDE users can not reactivate a task that is stopped by the operator with the ST command.
When you enter either an ST system command or a CANDE ?ST command, the task does not become suspended until it attempts to use a processor. Stopped WFL jobs do not become suspended until after the task started by that job terminates.
