You probably want it to look more like: define(`mymacro', `L`'bump(`counter')counter: mvi a, $1') > > But the output is not what I'd expect: > > 0 > 1 > 2 > [blank lines] > Lbump(counter)2: In your definition, you did not separate `L' from `bump', so m4 tried to expand the `Lbump' macro (undefined, so output as-is), then stripped the nested quotes. > mvi a, 3 > > Instead I need: > > L2: > mvi a, 3 With my definition, I added a `' after L to explicitly separate what is normal text from what I want to be a later macro call at time `mymacro' is expanded. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3266 Virtualization: qemu.org | libvirt.org
