> Can someone please explain me what is the transfer buffer?
DOS can't deal with protected memory. So, each time we need to talk
with DOS we have to use a portion of its memory space instead of ours.
The transfer buffer is a block of DOS memory we allocate and keep
around for all the different functions that access DOS (we move data
in to and out of the tb during many of the calls that deal with dos or
the bios). You can use it too, if you're careful not to call any
other functions that use it at the same time.
