1. You can check yourself (get dlsrc*.zip).

2. I haven't checked (see 1) but I would be very surprised if it
needed to call dpmi_int() as the operation is purely an updating of
memory.

3. If the processor would be returned to real mode, it would have to
be through a call to dpmi_int() (at least DJGPP would use that). No
"or" about it.

4. chaf undeclared.

5. Assuming you meant ch, there shouldn't be any reason for sprintf()
to bomb on that line.


Right,
