 move.w (doorsos::kb_vars+$1e), d0         ;move the key code into d0
 clr.w     (doorsos::kb_vars+$1c)               ;clear the keypress flag
;this moves the keycode into d0

;if you want a more sophisticated way try this. this will put a nul into d0 
if no key is pressed
 tst.w   (doorsos::kb_vars+$1c)        ;is there a key?
 bne     keypressed                   ;if yes.. go to keypressed
 clr.w   d0                                    ;clear the old key
 bra      nokey
keypressed:
 move.w (doorsos::kb_vars+$1e), d0         ;move the key code into d0
 clr.w     (doorsos::kb_vars+$1c)               ;clear the keypress flag
nokey:

hope this helps
