* 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!
