No flaming please, but I need help!

Two questions, one for doom, one for Duke3D. Now, before I start getting flamed for talking duke on Doomworld, I just want to say that I tried to get my answer from Dukeworld, ( Yes, there is a dukeworld. ) but I didn't get a reply for a week, and I know that there are a few dukers here, so...

In doom, how do you make a secret exit go to a secret level when making wads?

I got Duke in a pack of games with Tomb raider, total annhilation, heavy gear, and civilization 2. I looked on the CD in the goodies directory, and cannot find build. Help!

1) Assuming you use original doom[2].exe, The olny levels that can have secret exits are E1M4, E2M5, E3M6, E4M2, MAP15, MAP31

2) *trying to resist a flame* nope, don't know

* Myk sets his flame thrower at full power and incinerates LRM.

E1M3, not 4.

Sorry but for Duke I'm demoralized of this game, I always loved Doom since the beginning that I played him.
