   Thanks to both of you for your suggestions!   
      
   I was working on a TASKLIST + TASKKILL method of terminating the started task,   
   and ended up with:   
     :: the title can be any arbitrary string, which then appears in the list of   
   tasks   
     title %~n0   
     set forcmds=tasklist /v /nh /fi "imagename eq cmd.exe" ^^^| findstr /i   
   /c:"%~n0"   
     :: the PID appears as the second tasklist output field   
     for /f "tokens=2" %%a in ('%forcmds%') do taskkill /pid %%a   
      
   This works quite well, but Herbert's suggestion of   
     cd /d %temp% & start "" cmd /c "%~n0.bat"   
   means that I can use   
     exit /b 0   
   or   
     goto :eof   
   as the final statement in the batch file, and have this close the started task.
