Thanks to Harold and Jinx for their quick replies. Sounds good to me. I 
do have the MCLR tied high, and will plan to make it input, hadn't 
thought of that, that way. Thought I read somewhere that read that 
programming MCLR as output, could cause issues with in circuit 
programming, which I haven't been using. I have a Microengineering EPIC 
parallel programmer that has been doing OK with the 1320 chips. I had 
planned leaving RA4 floating, and just calling it an output.

And I had seen the notation for referring to  the registers before, but 
seem to get along better at this point with the bits.

 Thanks again. :)
