AFAIK, printf() doesn't output text at the position set by gotoxy(), but sends
it to stdout.

You must use the cprintf()/cputs() routines in conio.h to get text output at
the cursor position. CONIO.H has been ported for Djgpp, so you can use gotoxy(),
cprintf(), etc. without worries, and not worry about the buffering on stdout.

Curses is another possibility, but I've not had experience using it.

Adios
