 *  CALL.C - batch file call command.
 *
 *  Comments:
 *
 * 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.
 *
 * 10-Aug-1998 ska
 * - changed: initialize bcontext with function
 *
