Interesting point about WP / NP.
Seems many, many folks have used NPt for the "text editor" of choice for a long time.
Windows also has "EDIT", FWIW; I never use it.
I use a real DOS text editor.
You're correct in guessing that CHOICE may not be in the path. Hard tellin' where it might be.
But if CHOICE is not in the path, you'll get an error.
That's why I'm trying to get Mike to run it from a prompt.
If at first you don't succeed, you're about average.
