How to list tracks from 1-XY

Sorry if I am not clear with what I want. Difficult to explain.

I have many tracks (200+) which I simply want to have a track tag which has a algorhythm listing each track from 1-200 (It should list the numbers after the order they are in MP3Tag right now).

Hope someone knows a formatstring for this...
Coudln't figure it out myself but maybe I am just too dumb or don't know the exact word for the process I want to do.

Use the autonumbering wizard in Tools.

lol.

THANKS!!
That did it. Extremely easy to use... Wonder why I didn't stumble over this earlier but I never looked into tools. I always tried format strings...

Well thanks a lot, my problem has been solved!
