The MPASM User's Guide states "FILL ..... Generates <count> occurrences o=
f=20
program word or byte (PIC18CXX devices), <expr>."

I interpret this as bytes for the 18CXX devices, but words for all other=20
devices.  Guess I'll have to actually try it.

The 0's actually mean something to my application, which is why I need to=
=20
change them from the start.  Every time the circuit powers up, it will ch=
eck=20
the EEPROM locations for data saved from the previous time it was running=
=2E
