Timer

[Pfontvilanova]

Sorry for many questions. I would like to use in the forth lines the command like %time. It seems in the descriptions that maybe the similar is Timer, but i don’t know who to use it.
in jupiter notebook i easy:
%%time
%f ………………
Then you have the time for the instructtions.

How to do similar in forth? After peforth.ok()
Thank you.
