There is, of course, a way of hacking Bird's Better Bye out of ProDOS
and patching it into any new version of ProDOS.  "All" you have to do is
locate the QUIT code in the version of ProDOS you're using (with BBB),
and the standard code in the new version.  Then you can BLOAD/BSAVE or
whatever) the pieces and make a new version, complete with BBB.

It works...I've done it several times; I just don't have the addresses
on hand right now.  If people are interested, feel free to mail me.

Another solution is to use the QUIT routines that install themselves
upon running a SYS file.  SQUIRT (and I presume SQUIRT-16) do this.
Make SQUIRT.SYSTEM the first system file, and it runs, moves itself into
memory, and runs the next .SYSTEM file.  This kind of solution requires
NO effort when you change ProDOS versions.

...but I like BBB better. :-)

I suppose a great solution would be a patcher program, with the
addresses of the routines built in.  I can also see a patch for BBB that
makes it work like SQUIRT.  Neither of those would be too hard to piece
together, if I had the time.  Maybe later, if there's demand at all.
