<div style="word-wrap:break-word">I've run into a problem for which I can't provide a "minimal" example, but I desperately need advice.
<div><br>
</div>
<div>I have a long-standing book project which has gone through several revisions. It is organized in different .tex files pulled together by a master file; the current version has root file "CalculusThree14.tex". I don't want to discard earlier versions
until I am finished with revising, so I have all the files (except self-defined macros) in a different folder for each version.</div>
<div>The way I have been proceeding is to copy each file, then modify its name (the "14" distinguishes the current version from the previous one) and work with the current version (with all the calls to files not yet modified commented out in the master file.</div>
<div><br>
</div>
<div>So right now I have the file CalculusThree14.tex, and a long list of commands of the form \input{oldfilename} commented out, and others of the form \input{oldfilename14} which have been modified (or the same for the one file I am currently modifying).
When I create the new copy oldfilename.tex I change the first line from</div>
<div>
<blockquote type="cite">%!TEX root = CalcThree.tex</blockquote>
</div>
<div>to</div>
<div>
<blockquote type="cite">%!TEX root = CalcThree14.tex</blockquote>
</div>
<div><br>
</div>
<div>So far so good. </div>
<div><br>
</div>
<div>Except today, when I went to do this with the file previously known as integ2.tex, now incarnated as integ214.tex, I get the error message </div>
<div>
