Hi,

You DO NOT need to re-assemble the code ... simply told, you just use an HEX editor to modify existing lines or add some ASSEMBLER lines past the ones existing.
In MPLAB, you can easily do it in the "Program window" ...

The ABSOLUTE MUST is just not to modify the existing lines numbering ...

I've done it mostly to change the menu language ( just changing letters HEX code ... ) or add some I/O functions ...

Once more : do not worry ! ... turning to 877A is really easy. - turning to 887 would, of course, be a little trickier ...
