turboc - clrscr() & gotoxy() functions

[Paul Asmar]

	You have to initialize the screen with a built-in routine (initgraph()
I think), so that Turbo C can install the right graphics card (.BGI file).
You should look at the graphics help provided by Turbo C, and/or bgidemo.c
that uses most of the graphics tools, and is a good guide.
