Thanks Peter D, Ross M, and Herb S for your replies.  I'm sorry I didn't respond sooner; I receive the digest.

Umm ... I'm not sure, but I do use them all.  This is what I have in "narrowhom.tex" that is the main file:


[...list of \usepackage...]

\input{longdiv}    % use \longdiv{dividend}{divisor} for long division

\usetikzlibrary{decorations.pathreplacing}  % load tikz decorations library
\usetikzlibrary{calc}  % load the tikz calc library


% \includeonly{foo} processes/displays only foo.tex, keeping all refs intact

[...path to graphic files,
    list or \renewcommand, \newcommand, \newtheorem, &c....]


[...\title, \author, &c....]




% Bibliography

OK, I replaced '.' in the the chapter filenames to '_' (see my reply to Peter D above).

No, I uncomment only one \includeonly at a time.

I don't think so.  But here's something else I discovered, viz., if I comment out the line


then I do not get those other errors no matter which \includeonly is uncommented, so there must be something (but I don't know what) about the file "ch_numthry.tex".

They are before the \begin{document}; is that the preamble?

I don't know.  What should I be looking for?

Thanks again, y'all.  I really appreciate your time helping.
