You understand the word ``program'' too literally.  It doesn't
necessarily mean a complete executable; it might mean part of code
that is to be incorporated into a larger program.  As, in fact, it
turned out to be in this case: see the messages by the OP.

No, it's about drawing a character with DJGPP.

Portable to what?  Only to Borland and DJGPP, and nothing else.

`putch' invokes a real-mode interrupt (to position the cursor), and so
is very slow, hundreds of CPU cycles, due to the mode switch.
