`fflush's effect is only defined for output streams.  What Borland
does with "fflush(stdin);" is an unportable extension; you shouldn't
rely on it.

If you want to write code that reads characters one at a time, don't
use buffered input functions, they always read an entire line.  Use
library function `getch' or `getkey' instead.
