that should serve as an example for proper usuage.
In fact I needed a fast routine to increment the screen byte
at location (x,y) for a jigsaw-like puzzle-solver
to visualize the regions of current activity.

does it work with the INTEL- compiler ?
I need also a routine for the intel-compiler , since it is
about 30% faster on that program.
Our actual program runs with both compilers.

it adds to the other code. How large can it be ? 500K ?
Presumable it has to fit into low memory.
Large programs are also not so good to transmit by email.

it's useful to teach newbies proper usage of DJGPP :-)
(put it in the FAQ , to save others the time which I spent !)

yes, see above
