From Chapter 1.75 ENQ in the CICS Language Reference manual, link at the top of the page:
If a task enqueues on a resource but does not dequeue from it, CICS automatically releases the resource during syncpoint processing (including DL/I, PCB, and TERM calls), or when the task is terminated. Option UOW forces the dequeue at the end of a unit of work (UOW). Option TASK forces the dequeue at the end of a task. If there are several units of work in a task, the enqueue carries over the UOWs.
Is there some reason you could not do the manual research yourself?
