picaxe code help?

here is the code for a breathnalayzer using picaxe14m2 
ignore the if b2= as i have to experiment and get the values and i havent done so.
the code stores messages in eeprom and in the starting it operates a rgb led to create effects

the code:
low B.0'initialise lcd outpu
pause 500'wait for lcd to initialise
'load messages in eeprom
EEPROM 0,("NO ALCOHOL")
EEPROM 10,("ONE OR TWO DRINKS")
EEPROM 27,("BUZZED")
EEPROM 33,("DRUNK")
EEPROM 38,("WASTED")
EEPROM 44,("BLOW ON THE SENSOR FOR 5 SEC")
