Subject: Re: BDOS ERROR R/O, ARCHIVE BITS

Hi. There is a bug in the archive patch to the BDOS and there is a fix
for it (ARCHIVE.FIX). The note in ARCHIVE.FIX describes what you're
talking about. The fix is as follows:

       force$r$w       equ     bdos$entry+05BAh   ;force read write disk

       org             force$r$w

       ret             ; return from 'check changed disk'

I'm really not sure where in the patch that belongs but here is where I
put it and I've had no problems:

       wrt$dir equ     bdos$entry...
       scratch equ     bdos$entry...

       ; INSERT FIX HERE...

       org     wrt$dir
               .
               .
               .

Try it out. It should work. I've tried to get to Kelly Smith and get the
latest version of the program but he's moving and his system is down. If
you want a good rigid backup utility a friend of mine here reccomended
QBAX. It's only $30 and it has I/O redirection and a few other nifty
things. The new version of that should be out in a while and it will
even handle breaking up large files onto several floppies (so I'm told).
I'll be ordering it myself soon for a project I'm working on. Good Luck.
