Ralph,

All of those values are simply assigned to P1 and are used to control the 7-segment displays. I do not have any external chip to control the 7-segment displays. Every value of P1 is simply assigned to a segment on the display.

HOWEVER, please note that my wiring is probably not the standard way to wire a 7-segment display. If you are planning on doing something like this yourself, do not use my output values to P1 or you may find yourself more confused.

Also important, this is NOT the best way to do this. I have updated the source code with a much better way to display digits on the 7-segment displays without having to have a subroutine for every separate digit. When it is finally, working I will update it with comments and I will send you (or post here) a schematic if you like.
