Using same button for entering/exiting some part of code?

[amgen]

debounce button check... and instead of while-wend .... use for/next pause here is 2 second check so if holding button > 2 seconds, can advance MENUitem then check again for release


HERE:
IF UPBT=0 THEN
pause 50
IF UPBT=0 THEN ..............................#debounce check
MENUITEM=MENUITEM+1
IF MENUITEM>6 THEN MENUITEM=1
PAUSE 20

for a=1 to 20
pause 50................................................ ............# if 2 second press, advance item and wait again
IF UPBT=1 THEN ---leave to somewhere .................# XXXXX WHILE UPBT=0:WEND
next a
goto HERE

ENDIF
