Dear Sirs/Mesdames: I teach Computer Science here at Walsh University, and am planning to teach a new course using Haskell. My computer is a Dell Optiplex GXi with Windows NT version 4. I have Hugs 98, downloaded over a year ago. My download file is named "HUGS98-FEB2001.MSI" -- (I probably inserted the FEB2001 myself.) It installs without problems but at no time asks which editor to associate with HUGS. When I run HUGS and give the command :set, I read the following setting -EC:\WINNT\notepad.exe. Now I have Notetab light installed in C:\Program Files\Notetab Light\notetab.exe. So in Hugs I gave the command: :set -E"C:\\Program Files\\Notetab Light\\notetab.exe". When I then try :edit c:\temp\foo.hs, nothing happens that I can see. I restored the setting to its original form with notepad. Now :edit could no longer bring up notepad. I re-installed HUGS. Still the editor (with setting for notepad as installed) showed no effect when called. How can I set the editor to my preferred software notetab.exe? If I must manually edit the Registry -- something I have never dared to do until now, I would need to know where to navigate to! Many thanks ahead for your kind help!
