this is a tricky one. What is the editor that you want to start?
It must be runnable in the command line window, where the GAP is being
run. IMHO you cannot make Edit() to pop up a window for you.

Suppose you have such an editor, say "vi.exe", and it is on

Then set within GAP (or in .gaprc) the variable EDITOR:

gap> EDITOR:="/cygdrive/c/vi/vi.exe";

It should work then.

The reason for the syntax weirdness that Gap interfaces M$ Windows
via Cygwin (www.cygwin.com), a POSIX emulator; each Windows "drive"
is mapped to /cygdrive/"drive", and then you must replace \ by /
in the path...
