Well, everyone pretty much has his/her fave editor they get kind of attached to over time...
Personally I use nano, it is capable of saving to dos format... But it's an editor for in the shell -- so non-gui. Anyway I'm not really "up to speed" on the existing choise of editors since i'm quite content with nano. But surely there must be dozens available. Maybe try www.linux.org
they have a large list of linux apps sorted by category
Anyone else reading this know of editors capable of saving CRLF?
