I'm not sure about dsPIC-assembler, but for PIC16/PIC18, I think
that you have to have each routine in separate "modules". That
is, in separate .ASM files. Then all symbols become local to it's
own module and you have to use GLOBAL to actualy make them visible
in other modules (if you want/need that).

In your example, if Routine1 and Routine2 are in the same
ASM file, the assembler will give you an error.

Note that this *might* work different in dsPIC-assembler...

In a *macro* definiton, you can use LOCAL to declare local
symbols, but this wasn't any macro, right ?
