When you use an extended key, such as the Fx keys, etc., you will get
back first a 0 and then the extended code.  I'm not sure how Borland
does it, but I can't think it would be too differently.

Thus, you'd do this:

	switch( c=getch()) {
		case 'a': blah blah blah blah break;
		etc.
		case ' ': blah blah blah blah break;
		case 0:
			switch( c=getch()) {
				case 72: blah blah blah break;
				etc.
			}
		break;
	}

There are tables of what the extended key codes are, or you can just
experiment.
