Well, _most_ code would run unmodified.  There was a change in how
mid() worked between 1.0 and 1.1 which would prevent old code from
working.  (There used to be a PFMID=OLD, but that never made it to
filePro Plus, as I recall.)

Probably.  When "y2k" hit, lots of people came out of the woodwork who
were still on ancient filePro versions.  We still get the occasional
call from someone who is upgrading their ancient filePro because the
ancient hardware it's running on is dying.

And I keep a copy of filePro 1.1/1.2/3.0 around just for those people
who claim that "filePro didn't used to work that way".  :-)

However, I don't have the original tutorial files from that era to try.

I've got a dual 3.5/5.25 floppy drive in my system, though I haven't
used the 5.25 for quite some time.
