DELETE

The DELETE statement deletes all lines of text contained in the cache memory

associated with the specified task.

cache-taskid

identifies the cache memory that is to have its contents deleted. The contents are

deleted, not the actual taskid.

indicates that you want to perform the delete. Because the DELETE statement

completely destroys all data stored for a given task or set of tasks, the exclamation

point (!) is required.

Example

This example shows how you can use the DELETE statement to empty a cache so that

it can be used to programmatically generate a dynamic menu:

DELETE cache-taskid !

Note. The DELETE statement does not change a task's operational status. If the task was

running, it will still be running.
