I am using picbasic from MElabs and cannot get this code to compile:
Symbol TRISB = 134
Symbol PortB = 6
poke Trisb , 0
loop:
For B0=0 to 255
poke PortB , B0
Pause 250
Next B0
Goto loop
end

The code is out of the book by John Iovine

When I try to compile I get an error message on the "poke Trisb, 0 " command that says

ERROR LINE 13 ":" or "=" expected (Token 'Trisb') (count.bas)

Does anyone know why?
