Jan-Erik,
     I guess my next question is about packing the register. The RA0-1=20
and RB0-1 bits are my inputs. On Port A the output pins are 2-3 and 6-7.=20
On Port B it is 2-5. So if I have two output registers. One called=20
OutputA and the other OutputB. When the input is 0-0 then the output is=20
1-0-0-1. If the input is 0-1 then the output is 0-0-1-0. If it is 1-0=20
the output is 0-1-0-0 and if it is 1-1 the the output is 1-0-0-0. I=20
guess we should define some constants called Bit# such as Bit0, Bit1,=20
Bit2 and so forth to Bit7. These should be set to 1, 2, 4, 8, and so=20
forth up to 128. We first have to clear the registers to zero with=20
OutputA or B =3D 0; So do we add RA, B 0 and 1 together? And here is where=
=20
I get lost.  I just don't understand how to turn RA and B 0 and 1 in to=20
the proper number to put into the output bits. Would you please help me=20
with this.
Thanks,
rich!

P.S. This is how it should look.
