No, I am using the filename CalcThree (it was my error to refer to CalculusTree14.tex in my message..
<div>Anyway, problem solved by Ettore Aldrovandi (Thanks again).</div>

Maybe it is not related to your problem, but shouldn’t it be
<div class="">%!TEX root = Calc<font color="#ff4013" class="">ulus</font>Three14.tex</div>
<div class="">rather than</div>

<div class="">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 class="">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 class=""><br class="">
</div>
<div class="">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>
