>Theres old Fox for Dos app running on NT

Here are some strategies, I think you are young enough to pull these off:
1) reply "I have never used DOS" then run away.

2) reply "Isn't Microsoft trying to kill off DOS. Isn't version 6 the last version?" Then run away.

3) Fake a heart attack. In the ensuing confusion, run away.

4) Say nothing. Then run away.

5) Scream. Then run away.

Seriously though... It sounds like Ed and Walter have you on the right track.
