Arduino Analog Pins

Most microcontrollers allow the analog pin to also be digital by program configuration. Can this be done for Arduino boards in the IDE? There are lots of spare Analog Pins that I could use if it were digital.

Yes.
Use pinMode() to set them to input and then use "digitalRead(A1)" (for example. AnalogPinNumber+14)
(Um. It's on the reference page for digitalRead: digitalRead() - Arduino Reference)
