Andrew:

Define a conditional-assembly variable:

    DEBUG   SET     1       ;1 = Assemble for MPLAB_ICE,
                            ;0 = Assemble for a real PIC.

Then, in your code, replace the "SLEEP" instruction with:

        IF (DEBUG)
            GOTO    $       ;If we're running on the ICE,
                            ;just enter a tight loop here to
                            ;simulate being asleep.
        ELSE
            SLEEP           ;Otherwise, go to sleep.
        ENDIF
