: 
: .macro foo arg
: \arg:
: 	nop
: .endm
: 
: .text
: 	foo bar

Alternatively if the label is only ever defined and referenced inside
the macro you can use local labels like this:

        .macro foo
        99:
                NOP
                BNE     99b
        .endm

Of course this does not work if you want to nest the macro, or if you
are going to use the local label '99' somewhere else in your assembler
source, where it could span an invocation of the macro.

Cheers
