Hey Wolfgang. The reason why I hadn't done that is I didn't want to
overwrite the selected typeface I was using already for the main body
font. Isn't that what \setupbodyfont[mainface] would do?

In any case, when I add the following to my environment file...

\definetypeface[mainface][rm][serif][modern] [default][designsize=auto]
\definetypeface[mainface][ss][sans] [modern] [default][designsize=auto]
\definetypeface[mainface][tt][mono] [modern] [default][designsize=auto]
\definetypeface[mainface][mm][math] [pagella]
\setupbodyfont[mainface]

...I end up with the following error which, as usual, I don't
understand:

Underfull \hbox (badness 10000) in paragraph at lines 62--64

Here is the suspect file:

So what you are saying is that there is no need for \math whenever the
formulas are bracketed with \start and \stopformula? I will give this a
try as soon as I can get the book to compile.
