Make sure you don't call

Right, I meant to say, I'm not sure how to do it with JALLIB.
-- Eur's routine to read the A/D
var word analog
procedure get_analog is
ADCON0_NDONE = true
while ADCON0_NDONE loop end loop
analog = word(ADRESH) << 8
analog = analog + word(ADRESL)
end procedure
ADCON0 = 0b01_000_001
ADCON1 = 0b10_00_1110
forever loop
get_analog()
-- display on lcd
end loop

I just finished re-reading the Joep & Toon Tutorial. They explained the
answer to my question. ie to use the analog pins as digital IO
you have to disable them using the enable_digital_io(). what I had
read, but didn't remember, was that the non analog pins are usable any
way 'without' using the enable_digital_io() call.
So in my case I just have to use a digital pin for the LCD and an analog
pin for the adc and never call enable_digital_io().
Thank you Joep & Toon. Your Tutorial has helped me yet again.

Wayne
