   Understood, thank you very much!  So the redirection   
   itself does not affect ERRORLEVEL.  But why does the   
   following to:   
      
   @echo off   
   (type a > C:\NOSUCHNDIR\est.txt ) && goto OK || goto ERROR   
   :OK   
   echo All is well.   
   goto END   
   :ERROR   
   echo Error detected.   
   :END
