    I'm not sure what you want. The IR detectors simply output a "1" when they see IR light, and a "0" when they don't.
    If you are making a beam-break system, then when the output goes low an object has broken the beam.
    If you are making a reflective system, then when the output goes high an object is infront of the receiver.

    If you want code to generate the 38KHz, then use:

    IR_LED     PIN RA.0 OUTPUT ' Use whatever pin you want
 
INTERRUPT 76000 ' 2x frequency wanted
  IR_LED = ~IR_LED
RETURNINT

    Bean.

    Here's a program that will modulate an IR LED (per Bean's suggestion) and runs two servos in the background as well -- this should get you started.
