Subject: Is there a floppy in this drive?

  With thanks to Eli Zaretskii, I can now get a Gnu C++ program to find if a
floppy drive is empty without it wanting Abort/Retry/Fail. But the interrupt
that finds that, refers to drives by physical drive codes (0, 1, ...), not by
logical drive letters (A, B, ... or ditto minus 64 or 65). Some people have
more than 2 floppy drives: I heard of someone with floppy drives A: B: C: D:,
and his hard disk was E:. Are there any cases at all when the logical floppy
drives A: B: etseq in that order are NOT physical drives 0 1 etseq in that
order? Are there any cases when the floppy drives' logical drive letters are
not all the first letters of the alphabet?
  It seems that under Novell there can be 32 drives: A: to Z:, and [: \: ]: ^:
_: (the five ASCII characters next after Z:). That makes 31 drives; is the
remaining one @: (the character before A:), or `: (the character after _:)?
