room counter program in codewarrior

I need a program built to be like a room counter that will work with the Dragon 12 Light board. It has to ask for identification and use the dip switch to accept and not. Ask how many people are in a group, using dip switches enable the LEDs to display the number of people in the group. The LCD will display how many people have entered the room. The LCD will ask how many people have left, use dip switches to how many have left, if any.
