To delete a breakpoint via the command window, first issue the show events command. This prints out the event list. Each event has an ID number associated with it.
To delete one or more of these events, issue the delete command, listing the ID numbers of the events you want to delete; separate multiple IDs with one or more blank spaces. For example,
delete 1 3
deletes the events with IDs 1 and 3. Use the argument all to delete all existing events.
