   I want to copy an HTML page file to another file, omitting both the   
   heading+introduction and the tailpiece.  For test I use a line of four hashes   
   as separator, and a test file :   
      
   head   
   ####   
   want   
   ####   
   tail   
      
   My non-working test code is in :   
      
   @echo PRUNE.BAT JRS 2021-11-30+    ???   
      
   @echo.   
   @if not exist zzz\nul mkdir zzz   
   @echo 1111   
      
   @SET ZC=0   
   @echo. Start >  ZZZ\ORIG.HTM   
   @FOR /F "eol=; tokens=*" %%J IN (PRUNE.DAT) DO @(   
     @echo Comment line='%%J'  ZC=%ZC%   
     if [%ZC%] == [1] (   
       echo       '%%J'  >>  ZZZ\ORIG.HTM   
       )   
     if [%%J] == [####] (   
       set ZC=1    
       echo === %ZC%   
       )   
     @echo ++   
     )    
      
   @echo 9999   
      
   @echo. Ended >>  ZZZ\ORIG.HTM   
   @echo.   
      
   type ZZZ\ORIG.HTM   
      
   @echo PRUNE.BAT ends.   
      
   The apparent problem is that the line     set ZC=1    has no effect, so that   
   the wanted part is not copied. ( I intend to change it to    set /A   
   ZC=1+%ZC%       which should mean that the tail part is not copied).    
   Subsequently I may use a line         
    as an invisible separator.   
      
   What's wrong?
