   3  *  CALL.C - call internal batch command.
   4  *
   5  *
   6  *  History:
   7  *
   8  *    16 Jul 1998 (Hans B Pufal)
   9  *        started.
  10  *
  11  *    16 Jul 1998 (John P Price)
  12  *        Seperated commands into individual files.
  13  *
  14  *    27-Jul-1998 (John P Price <linux-guru@gcfl.net>)
  15  *        added config.h include
  16  *
  17  *    04-Aug-1998 (Hans B Pufal)
  18  *        added lines to initialize for pointers (HBP004)  This fixed the
  19  *        lock-up that happened sometimes when calling a batch file from
  20  *        another batch file.
  21  *
  22  *    07-Jan-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
  23  *        Added help text ("call /?") and cleaned up.
  24  *
  25  *    20-Jan-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
  26  *        Unicode and redirection safe!
