gee, that example is confusing. all i want to use is 5 buttons on port c of my 16f873.

button A = High Setpoint
buttonB = Low Setpoint
buttonC= Increment
buttonD= Decrement
buttonE= Return to main display

At power up of my device, I want my program to prompt the user to enter a high and low setpoint then continue to display the main program afterwards. If the user decides to change setpoint, then the buttons above can be used.
