11.3.255 zip/0   development

Synopsis

zip

Turns on the debugger in zip mode.

Description

zip/0 turns the debugger on and sets it to zip mode. Turning the debugger on in zip mode means that it will stop at the next spypoint encountered in the current execution. Until the spypoint is reached, it does not keep any information of the execution of the goal, and hence you will not be able to see the ancestors of the goal when you reach the spypoint.

The effect of this predicate can also be achieved by typing the letter z after a ^C interrupt (see Execution).

Exceptions

None.
