Ummm yes, well if you are running a 16-bit DOS environment,
and all you want is super low resolution character output,
but this is definitely a gasp-from-the-past

(by the way, this is not somehow some secret programming trick
known only to obscure Japanese programmers, it was absolutely
standard in early DOS days). Of course very few Ada compilers
ever operated in this kind of environment (RR and Janus only)
