I/O - From Define to code ... must be easy

[cncmachineguy]

I think the preferred way is this:

LowBeerLevel var portb.1
GoToBeerStore var portb.2
 
while !LowBeerLevel
   :):)
while end
 
ASM
BSF _GoToBeerStore
ENDASM
 
If GoToBeerStore = 1 then
  :(

Ok, silly example, but the point is create your var's or alias as usual, then to use in ASM block stick an underscore before the name.
