limiting to "no less than" zero

[Heckler]

This Should (untested as of yet) work...

One thing about programming... there is always more than one way to do the exact same thing... some are more elegant than others... Mine usually falls into the "less elegant, but gets the job done" category

The extra "IF" test should eliminate the need to test for below zero or the "max 0" test.

volume = 100        'set a default level
 step = 3            'This could be ANY NUMBER FROM 1 TO 9

 
 main:

 if buttonA  then volume = (volume + step) min 350     'this works fine to limit the top end to 350
 
 if buttonB and (volume < 3) then  
      volume = 0
      goto Skip1
      endif  
 
 if buttonB  then volume= (volume - step)         'but of course THIS fails, because it's hard to go lower than zero

Skip1:
 LCDOUT $fe, $c0, dec volume

 pause 50
 goto main

 end
