Look up the LOCAL directive.  You can use it instead of manually making
unique labels.

You are also overthinking this regarding PAGESEL.  The 18F branch
instructions are relative, and only allow for a small range.  You wouldn't
use them accross code sections anyway.  I don't know if the linker/assembler
has support for fixing up offsets for those instruction accross sections,
but even if they did most of the time the target would be too far away.

So here is all you need:

bnz      macro   target      ;like 18F BNZ instruction
         btfss   status, z   ;is zero ?
         goto    target      ;no, do the branch
         endm

One gotcha with this is that the BNZ macro can't be used immediately after a
SKIP, unlike the real BNZ instruction.
