   If without passing some information as a batch file parameter is your only   
   requirement, then you can use either environment variable or a file instead.   
   e.g.   
      
     ::Caller.bat   
     ::using environment variable   
     set caller=%~n0   
     call called.bat   
     goto :eof   
      
     ::Called.bat   
     ::using environment variable   
     echo Called.bat was called by %caller%   
     goto :eof   
      
     ::Caller.bat   
     ::using file   
     >"%temp%\caller.tmp" echo %~n0   
     call called.bat   
     goto :eof   
      
     ::Called.bat   
     ::using file   
     for /f "delims=" %%A in (%temp%\caller.tmp) do (   
       echo Called.bat was called by %%A   
     )   
     goto :eof
