          WARNING: Do not start terminate-and-stay-resident (TSR)
                   programs in a shell. This causes unpredictable
                   results.
 
     Arg Shell («arg» «shell»)
          Runs the text from the cursor to the end of the line as a
          command to the shell, and returns to PWB.

     True:  Shell ran successfully.
