   It depends on your OS.   
   Pure MS Dos is not suitable for multitasking.   
   What happens is that the focus simply passes from one program to   
   another. So program 1 may start program 2, which may start program 3. As   
   long as program 3 remains active, programs 1 and 2 remain inactive.   
   Close program 3 and you are back in program 2.   
   In order to have a multitasking system, you must find a way to divide   
   processor time between the different processes. Perhaps you can switch   
   the focus without unloading when you make the separate processes TSR.   
      
   If you run a program in a dos box, exec may start a new program as a   
   separate process. E.g. You can call the windows Notepad editor, which   
   will open in a separate window and gets the focus. If you click of the   
   dos box again, it gets the focus and continues runnig without closing   
   the notepad window.
