   5  *  History:
   6  *
   7  *    16 Jul 1998 (Hans B Pufal)
   8  *        started.
   9  *
  10  *    16 Jul 1998 (John P Price)
  11  *        Seperated commands into individual files.
  12  *
  13  *    27-Jul-1998 (John P Price <linux-guru@gcfl.net>)
  14  *        added config.h include
  15  *
  16  *    04-Aug-1998 (Hans B Pufal)
  17  *        added lines to initialize for pointers (HBP004)  This fixed the
  18  *        lock-up that happened sometimes when calling a batch file from
  19  *        another batch file.
  20  *
  21  *    07-Jan-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
  22  *        Added help text ("call /?") and cleaned up.
  23  *
  24  *    20-Jan-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
  25  *        Unicode and redirection safe!
  26  *
  27  *    02-Apr-2005 (Magnus Olsen) <magnus@greatlord.com>)
  28  *        Remove all hardcode string to En.rc
