Thanks.  I did this:
C:\>where python
C:\Lilypond2221\usr\bin\python.exe
C:\Users\Archer\AppData\Local\Microsoft\WindowsApps\python.exe
(I ran this this Python from the command line and it said it was version 
3.6)

I also downloaded and installed Python3.9.  This time when I ran my 
batch file, Windows asked if I wanted to open the .ly file with 
Python3.9.  I said OK.  I wonder if it tried to run Python directly.  
Anyway, something happened, and then I was back to:

C:\P3L\lpbk>C:\Lilypond2221\usr\bin\lilypond-book --output=out --pdf 
ALMdurasnumber.lytex

C:\P3L\lpbk>cd out

C:\P3L\lpbk\out>pdflatex ALMdurasnumber.tex
This is pdfTeX, Version 3.141592653-2.6-1.40.23 (MiKTeX 21.7)
entering extended mode
! I can't find file `ALMdurasnumber.tex'.
<*> ALMdurasnumber.tex

Please type another input file name:
! Emergency stop.
<*> ALMdurasnumber.tex

!  ==> Fatal error occurred, no output PDF file produced!

Terminate batch job (Y/N)? y

with no complaint about "can't access".  Maybe my OK re opening with 
Python was incorrect.

Still struggling, but very grateful for your help.
