stop


command. Ends the running of the procedure in which it appears. Control is returned to the context in which that procedure was invoked. The stopped procedure does not output a value.

Example:

to t forever [if key? [stop]] pr [Hallo!] end ;t defined t

Then, if you press any key t will stop and the pr will not be run, because stop immediatly exits the currently running procedure.
