LCD R/S works on Port A but not Port B

Try adding this to your code. FLAGS=0 and for the 627A add cmcon=7 to disable the comparators on portA. It is just me but I would initialize the Ports before the Tris with PortB = 0 and PortA = 0 and lose this: OPTION_REG = $80. OPTION_REG = $80 sets WPU when portB is set as input, since you are using it as outputs, it is not needed.
