Seems like a lot of work to rewrite a program to use a different Case, when you can just turn off case sensitivity for MPASM, and use any case.

For MicroCode Studio Plus:
From View | Picbasic Options... | Assembler Tab and Options tab
uncheck the "Case sensitive" Checkbox
Press OK
The Microchip MPASM checkbox must be checked to see the Case option.

For other editors, or dos:
Add -c to the MPASM command line.
