Only internal code can be executed on any PIC that I'm aware of, BUT...
the 16F87x series can write its own FLASH program space.  A guy could
store code in an external EEPROM, reaqdd it and write it to program space,
then execute it.  You'd have to watch the number of write cycles, though,
or you could (in theory) kill the program FLASH.  That's the only way I
could think of other than using the EEPROM to store tokenized code to be
executed by a program running from the PIC's internal memory, like the
BASIC Stamp.
