How does a custom exit work?

[Kalaron]

How do you make a level use a custom exit and make it go to a different level other then the one specified in the MAINCFG lump of the wad?

Please tell me how to do this.

The Wiki explains everything you need to know for this (and most other things, come to that): http://www.srb2wiki.sepwich.com/index.php?title=Linedef_Type_71.

I'm sorry for waisting your time, I figured out how to do it on my own.
