68K Professional Text Editor

[Oldsmobile_Mike]

Your post is confusing.  Might want to specify whether you're looking for a text editor (Ed, Cygnus Ed, etc. - used for entering code, editing your Startup-Sequence, etc.), a word processing program (KindWords, Final Writer, Amiga Writer, etc., used for general document creation), or a desktop publishing program (PageStream, etc.).  Oh well, plenty of options out there, in all cases.  Good luck!

What would you recommend for writing a book?
Could Page Stream make an online magazine?

Amiga Writer, or Final Writer, or something of the like.  There's been some recent developments in that department, you might check on this thread, and those of the like:  http://www.amiga.org/forums/showthread.php?t=69443


AFAIK PageStream can't export HTML, so it's not going to work for making an "online magazine".  But newer versions are supposed to be able to export PDF, so it could work that way.
