OpenDOS is probably case-insensitive in the same way CP/M is: it converts the
command line to uppercase and trusts the program to do the right thing. CP/M
does not convert the file name in an FCB you hand it to uppercase, it just
goes ahead and uses it.

The traditional way of deleting this sort of file in CP/M is to load MBASIC
and issue kill "MAiN.tXT"; MBASIC does not uppercase file names and is therefore
both the leading creator of filenames with lower case and the easiest and
quickest way to deal with them. If I ever experimented with GWBASIC to determine
whether it worked this way, it was so long ago that I forgot the result...
