Thank you once more.

I needed to remove the dvipdfmx global option on my system and then it ran just 
fine.

The above worked as well after I changed [nomath] to [no-math] on my system.

The "LaTeX Companion" (2ed) on page 841 advises

"It is important that you exclusively use the LaTeX constructs described below, 
rather than the lower-level TeX commands."

This was behind my previous question on LaTeX equivalents for TeX commands. Now 
that you have demonstrated the power of the direct TeX commands, I am encouraged 
to experiment modularizing the above into a standalone package.

It is very useful to know this. Thanks.
