I am just trying to make a simple text mode, move around demo.  Having a
Zero move around the screen when you press 8(up), 6(right), 4(left), and
5(down).  It compiles ok, but then when run, if you press any of the
above keys it repeptitively prints the zero key until you end it(press
escape). Please if anyone see's the problem in the following code,
e-mail me at: slanker505 AT usa DOT net.  Thanks in advance.  Reply by e-mail
please..

variable to get the keypress */
                your_character=48; /* Ascii code for zero 0    */
