Go4Expert - 6800 assembly code

Hi everyone. I have a little problem. I have some versions of the same code I would like you to have a look at. The task is to display the amount of X's across the screen and the same amount of lines, that corresponding to the the key you press. eg
if the key press is 2 then it will display
XX
XX
I have got an idea of how to do it. But when I try and store the key presss in the variable at the start of the code after I get the keypress it stops my programming working probably. I have declared a variable called keyPress .byte 0
Here is one version of the code.

Code:

 

; Initialise constants 

lowerBound .equ '1

upperBound .equ '9

count .equ '0

spaces .equ 54

;

; Get keypressed from keyboard

 ldx #$FFFF  ;keyboard

 wai

;

;Load the key pressed into AccA 

 ldaa 0,x

; staa keyPressed

 clrb

 tab

;

 cmpa #lowerBound

 blt finish ; branch to finish if key press is less than lowerBound

;

 cmpa #upperBound

 bgt finish

;

 ldx #$FB00

 ldaa #'X

loop1 staa 0,x

 inx

 inc count1

 decb

 cmpb #count

 bne loop1

;

loop2 ldab #spaces 

 inx

 inc count1

 cmpb count1

 bne loop2

; 

;

count1 .byte 0 ; to compare spaces

keyPressed .byte 0

lineCount .byte 0

;

finish .end
