/*
 *  CALL.C - call internal batch command.
 *
 *
 *  History:
 *
 *    16 Jul 1998 (Hans B Pufal)
 *        started.
 *
 *    16 Jul 1998 (John P Price)
 *        Seperated commands into individual files.
 *
 *    27-Jul-1998 (John P Price <linux-guru@gcfl.net>)
 *        added config.h include
 *
 *    04-Aug-1998 (Hans B Pufal)
 *        added lines to initialize for pointers (HBP004)  This fixed the
 *        lock-up that happened sometimes when calling a batch file from
 *        another batch file.
 *
 *    07-Jan-1999 (Eric Kohl)
 *        Added help text ("call /?") and cleaned up.
 *
 *    20-Jan-1999 (Eric Kohl)
 *        Unicode and redirection safe!
 *
 *    02-Apr-2005 (Magnus Olsen) <magnus@greatlord.com>)
 *        Remove all hardcode string to En.rc
