>The exchange of CygnusEd source code broke down years ago
Exchange? What's that mean? Did a different programmer take the help at some point?
Many years ago I bought some version of CynusEd (Pro?). I can't even remember the full name or version, but even on a barebones A1000 that program flew! Dog, how I loved that program! Between it and various Amiga shell programs (and some unix shell commands ported to the Amiga) I could do some amazing things.
