Andy Beat me to it, but below I've put in a little program I wrote to
demonstrate how duplicated labels can be used in MPASM.

Note that doing this can make your program pretty difficult to understand
when looking at the listing.

;  This is a simple Program to test local labels in a Macro.

;  Hardware Notes:
;   This is program will not be loaded into a PIC.
