SOLVED - Can't get IOC on pin change working

[Demon]

I removed INTCON and PIE0 as per:

The HeartbeatLED doesn't hang any more, but the ISR doesn't seem to get triggered.

Richard gives me hope; the 16F18875 is part of the same family as the 16F18877:

You need to redo the section that #defines the interrupt bit locations.
It's in the section that looks like this...

  #define INT_INT      	PIR0,INTF,  PIE0,INTE       ;-- External INT
  #define IOC_INT      	PIR0,IOCIF, PIE0,IOCIE     ;-- Int On Change       *

You need to get the datasheet for the part and change the 'PIR0,INTF, PIE0,INTE' statements to match.

I have no idea what section of the datasheet I'm supposed to be looking at.
