Tim,

in datasheet page 175 if master clear pin is enabled
Then RA5 input is disabled when you program the part
In configuration window change that.
Also in mplab verify  TRISA and ADCON1 in SFR window.
I checked the datasheet and I liked this part nono watt
Technology enhanced eusart, CCP and more I think I am going
to move to nono watt technology soon.

Thanks Olin

I have the OSC set as HS and it runs at 4 mhz


The basic code in the sim looks like this:-

        Movlw 127
        Movwf ADCON1

        btfsc PORTA,5
      goto  handle_high
      goto  handle_low


handle_high
     goto $

handle_low
     goto $
        END

In the main code it does a bit more but is essentially the same


BTW
    I am aware of the LVP issue with some 18F devices and I don't have
LVP
set on.

Tim

If the configuration bit is set properly, then RA5 is an input instead
of
MCLR.  Note that it can not ever be an output.  There is no TRIS bit for
RA5.

What oscillator configuration and speed are you using?
