1 /ENTRY
/ENTRY=entry-number Identifies the job by the system-assigned entry number. The system assigns a unique entry number to each queued print or batch job in the system. By default, the PRINT and SUBMIT commands display the entry number when they successfully queue a job for processing. These commands also create or update the local symbol $ENTRY to reflect the entry number of the most recently queued job. To find a job's entry number, enter the SHOW ENTRY or SHOW QUEUE command. If you specify both the job-name parameter and the /ENTRY qualifier, the job name is ignored.
2 /QUEUE
/QUEUE=queue-name[:] Names the queue containing the job. If you use the /QUEUE qualifier, you must specify either the job-name parameter or the /ENTRY qualifier. If you specify the job-name parameter, the default queue is SYS$BATCH. If you specify the /ENTRY qualifier, there is no default queue. If you specify a generic queue, the command looks for the job in the generic queue and in the generic queue's target execution queues.
3 /TIME_OUT
/TIME_OUT=n Allows the user to specify the number of seconds to wait before terminating the SYNCHRONIZE command when the target job is running.
