count and number instances of a character in sed or awk
I currently use LaTeX together with a sed script to set cloze test papers for my students. I currently pepend and equals sign to the front of the words I want to leave out in the finished test, =perpendicular, for example. I am able to number the blanks using a variable in LaTeX. I would like to switch from using LatTeX to using groff typesetting.

My question is this: can I label or replace the equals signs with a running count with sed or awk, or even troff/groff for that matter? If so, how might I do it?

Thanks

HISTORY

       The GNU shtool subst command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 2001 for GNU shtool.  It was prompted
       by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications.

SEE ALSO

       shtool(1), sed(1).
