   I was updating a batch file I wrote to backup one of my PCs.  It kept crashing   
   at a certain point.  For two days I tried various things to fix it with no   
   luck.  I finally guessed at a fix which does work but I don’t understand   
   what the problem was or    
   why the fix works.  Here are a few lines from the batch file showing the   
   original version.   
      
   (It’s basically a counter/timer loop.  When the counter hits 5 seconds it   
   exits the loop and continues elsewhere in the batch file.  It’s the bottom   
   line that caused the crash.)   
      
   =================================   
   :wait-Z   
   if %counter%==5 goto Start-N   
   timeout 1 > nul   
   set /A counter=%counter%+1   
   if not exist z:\transfer\batch goto wait-Z   
   =================================   
      
   The fix: in the top line and the bottom line I changed “wait-Z” to “wait   
   ZZ”   
      
   The same thing happened elsewhere in the batch file with “wait-O” which I   
   had to change to “wait-OO”.  The problem does NOT happen with   
   “wait-N”, “wait-P” or “wait-Y”.   
      
   I’m just trying to understand what’s wrong with “wait-Z” and why   
   “wait-ZZ” works fine.   
      
   Possible clue: this happens on only one of my PCs.  It’s a new one I built   
   about two weeks ago.  All else seems to be normal with it.  Windows 10 Pro   
   64bit.   
      
   Thanks!
