Thanks Jack. I read that a few times I kept missing it. "But the first
letter isn't a digit!" I said to myself. (Facepalm)
That will probably work for me. I liked the dollar sign because it is more
obvious than an underscore but maybe it is not portable to other versions of
m4. I will check that.
Thanks to you and Eric for the explanations. It is working fine now with
underscore, and I am quoting the macro names as Eric suggested.
