And in article <315@unmvax.unm.edu>,
    brainerd@unmvax.unm.edu (Walt Brainerd), writes (quite correctly):

    * Two things to watch out for.

    * 1.  Make sure you put it thru tbl first (before eqn).
    * It worked fine on my system.

    * 2.  Make sure you use a symbol for the eqn delim that is not
    * generated by tbl (as a funny register name, for example).
    * This can be tested by running:

	   * tbl <file> | grep %

You also might want to change tbl's options line to read:

	center delim(%%) ;

so that  tbl  knows about the delimiters that  eqn  is using
for in-line equations.
