Keyboard input not working correctly

I am able to turn the screen black but i feel in my code the keyboard input is not being read properly.Can't seem to figure out why from a long time.I was hoping someone could give me a little insight into this problem.Here is my code.

[Problem solved--source code removed by admin.]

//	if addressi=anything other than 0 GOTO LOOP3
@addri      // A=16
D=M         // D=24576
@LOOP3
D;JEQ       // never jumps

addri is storing a pointer to the keyboard (like addro is a pointer to a screen word) so you need to dereference it.  It is easier eliminate addri and to just use SCREEN here directly.

After you have solved your problem, please edit your post to remove the otherwise working code.
