   Not actually wrong, as it shows that %ZC% is not returning what I want;   
   and so explains why the next line,    if [%ZC%] == [1] (   , is not doing   
   what I wanted it to do  .

   It does.  I copied the whole lot, and it ran.  All that I now want is to   
   arrange that the second #### sets ZC to something other than 1, which should   
   be easy (P.S. it was : set /a ZC=1-!ZC!).  And I don't want the #### marks to   
   appear in the output as    
   rendered on the screen, but using       instead should serve.   
      
   I control the input file; I can alter its content in any way that does not   
   adversely affect what appears on the screen when the HTML is rendered.  The   
   present part, a pre-processor,  just copies the HTML unchanged (I hope), but   
   omitting blocks that I do    
   not want in the output.

   Understood.  No problem here.  It is the code which runs next that handles the   
   HTML; it copies the wanted lines, which are those containing the name-strings   
   provided as arguments, and separately lists the contents of the first   href="   
   ... ">   in each    
   of those lines for XCOPYing as in my previous thread here.  As the input is   
   HTML, if there is a second such link on one of those lines line I will just   
   insert a newline in the input - I think.   
      
   Thanks again!                    |
