Paul,

   I've read the m4 man page, info file, and manual (the .pdf version of the
info file) without seeing how I would set up the input files. I assume that
one file contains two tokens, NAME and ADDRESS, but how are they separated
on each line?

   The other file, newsletter.m4, I assume begins with:

GREETING,

   This is the text of the newsletter.

Is this correct?

   Trying to find examples by searching the Web turned up lots of Microsoft
examples but none using GNUm4.

Thanks,

Rich
