OK,  I surrender.  I tried all the searches I can think of and I need 
to find the command that takes all the input states of a port and 
makes it a single binary number.  I looked in my codevision help 
section and no help there either.

The input is 12 bits arranged in groups of three so I plan on using 6 
inputs in port a and 6 in port b and convert each six into one big 12 
bit number.   then I use the 12 bit number to compare to a value in 
an array and output an equivalent decimal.  

Can anyone give me a clue.

thanks

Jim

Huh?  Each port IS a binary number.  Just read the port.

I don't know of any specific commands because each port is stored as a
binary number so there really is no need to convert it.  So if you use
two ports you will have a low byte and a high byte, one will be port a
and the other port b.
Ie: 
Mov R20, PINA
Mov R21, PINB
