Looking for a good full-screen editor

[Indiana Joe <indianajoe3@comcast.net>]

 I'm playing with Catakig, and want to start typing in some of the 
programs from Nibble. I'm looking for a full-screen program editor. I 
have a copy of Boston Window, but no manual. I also have the source code 
for the Applesoft Turbo Editor (Nibble, June 1987), but I can't figure 
out how to start a new program in Merlin, and I don't know how to 
convert Merlin's pseudo-ops to something Edasm will handle (and I'm not 
typing 1300 lines in without some idea of where to go).

 So, any suggestions?
