   Your  solutiuon works indeed, but I don't understand   
   the explanation:   
      
   > type resets the errorlevel to 0 on success, so set it   
   > to 1 before you execute type.

   > type a > C:\NOSUCHNDIR\est.txt   
   > IF ERRORLEVEL 1 goto ERROR   
   > echo All is well.   
   > goto END   
   > :ERROR   
   > echo Error detected.   
   > :END   
   >   
   > goto :eof   
   >   
   > :set_err   
   > exit /b %1   
      
   The line   
      
      type a > C:\NOSUCHNDIR\est.txt   
      
   contains two actions: an invocation  of  `type'  and   
   the  redirection of its output to a file.  If `type'   
   resets ERRORLEVEL on success, why does the  previous   
   value of ERRORLEVEL matter?  If a failed redirection   
   sets ERRORLEVEL, why does the result of `type'  mat-   
   ter?   Perhaps I misunderstand the sequence in which   
   the shell executes that line...
