	Just a few corrections ...

	That should be "w" for write, rather than "r" for read.  Also, using
"w" without a file name will write to the file specified when running Z -- no
need to type out the entire filename each time (I hate typingk).
If you didn't give a filename (perfectly legit) it responds "Can't open output
file" (I just tested it -- ah, multi-tasking).

	Use the "q" command WITHOUT the "!" and Z will protect you from
throwing away your changes by refusing to quit.  Using the "!" in the
command ( as in "q!") over-rides this protection.  You would use the
over-ride in cases when you DON'T want the file saved to disk (like
when you screwed up your file and DON'T want it saved, or like when you
just want to read a file).
	It amazes me that many Amiga applications don't even give you this
simple form of protection.

	I've never had any problems and have never used the ZZ command
(well, maybe once or twice when I didn't know what I was doing.  :-)

Flipside,
