yeah, it's actually pdoxwin running, but that shouldn't matter.. I figured 
that changing the file with notepad would break it.. the "dirlock" result 
was a surprise.. it's definitely not a dirlock :-)

this stupid old laptop, which is about to be replaced, thinks there's an SD 
card in F:, and I can't delete, uninstall, etc.. that's why I tried changing 
it.. I'll send a copy of the files to your email.. if you can change F to C, 
or run them as F on your machine, that would be great

Steve,

It might take me a few shots to recall some useful details...

Probably irrelevant, but are you using PDoxDOS or some version of
PDoxWin? Or both  ;-)

This was a very major issue, some decades ago. And now I don't recall
the causes/solutions. Perhaps Locks are being placed, but not released.

Sounds perfect.

Maybe try SUBST to assign the required letter - if that letter is free.

When you change the Drive-letter, make sure you use a "hex" editor - a
standard editor would likely mess up a hex-editing session. Also, the
drive-letter might be held in multiple places inside a hex file, perhaps
as a letter a-z, A-Z, and/or as a number (0=A, or 1=A, or 0=C, or 1=C, etc).

When investigating this issue way-back-when, I wrote some code to
analyse the lock-files. The only detail I recall now is that the code
searched for pairs (Lock and Unlock) within the file, and then
highlighted the unmatched/unreleased locks/entries. I'm sure I have that
code somewhere, if it might help (I might even have previously sent it
to you/others!).

Or, if you want, send me the Lockfile, and I'll check if I can access it
here.

The Directory-Lock message seems wrong - that was/is an option to place
a lock on a Directory, and thereby avoid having to place/release all the
individual record/block locks thereafter.
