RUN commandline

* RUN  executes  a commandline in a background task. If you want to
  execute several commands, you can separate them with ; .
* By default output goes to the current window. To surpress output or to
  get it into a file or onto a different window you can use  redirection 
  symbols like ">" (no output), ">filename" or ">w" (to a new window).
  In case of output redirection the launched background task will be
  totally independent from the task it is launched from.
* Input will be redirected to the same window output goes to. If you
  redirect output to a file, no input is possible (redirected to NIL:).
  Input redirection symbols does not make sense with the RUN command.  
* Because most things will be inherited to the new shell, you can use
   Aliases .

eg.     run copy fred.doc prt:
        run >prt: type barney.doc
        run >w dir df0:;ask
