* hb_slex.vc
     * Minor corrections.

   * include/hbapi.h
     + extern PHB_ITEM hb_paramError( int iParam ); /* Returns either the generic parameter or a NIL item if param not provided */
     + extern PHB_ITEM hb_arrayFromStack( USHORT uiLen ); /* Creates and returns an Array of n Elements from the Eval Stack - Does NOT pop the items. */
     + extern PHB_ITEM hb_arrayFromParams( void ); /* Creates and returns an Array of current Generic Parameters. */

   * include/hbapierr.h
     * extern USHORT   hb_errRT_BASE           ( ULONG ulGenCode, ULONG ulSubCode, char * szDescription, char * szOperation, USHORT uiArgCount, ... );

       + Added support for variable number of Error Arguments.

   * source/vm/arrays.c
     + PHB_ITEM hb_arrayFromStack( USHORT uiLen )

   * source/vm/classes.c
     + Added 0 arguments (J.F. can you please decide what should be the arguments! )

   /* HBTEST now reports 173 failures ( down from 376 ) many of the failures are justified.

      I have tested this as much as I could, but since it invloved lots of "Cust & Pasets" more testing should be done.

      It would be great if someone could review each of HBTEST Reported Failures on a one-by-one basis.

     BTW, HBTEST reports 1 UN-RELEASED Memory Block (from before my changes)!
