+/* $Id$
+ *
+ *  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 <ekohl@abo.rhein-zeitung.de>)
+ *        Added help text ("call /?") and cleaned up.
+ *
+ *    20-Jan-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
+ *        Unicode and redirection safe!
