I ran your testme.ex in a Win95 DOS window and it ran
perfectly. When I restarted in plain DOS mode, it gave:

     "Could not open testme.ex"

number of bytes read = -1
and also "t" and "e" as you saw.

Note that the bytes read was -1 (minus one) *not* 1.
That means it failed to open the file.

I don't know why the program failed under plain DOS,
but Jacques' code seems to use a different DOS interrupt
depending on the version of DOS that it thinks it is running on.

I'm pretty sure that people have run Jacques code on plain DOS
before without a problem, e.g. games, sound blaster etc.

I guess you'll have to consult with Jacques, or someone who
knows about DOS interrupts. Maybe he's trying to use a
long filename interrupt for opening a file, when plain DOS
on Win95 doesn't support long filenames.
