     ! Fixed to use HB_ISNUM() instead of HB_ISNIL().
     % Don't call HB_ISNUM() where the default value is
       zero anyway. hb_parn*() functions will return zero
       anyway. (well, maybe this exploits the array-type
       bug in our Extend API.)

     * Avoiding ISNIL(). Corrected just a few occurences.
       This practice is still wrong in most of the cases in
       GTWVG code, so if the goal is GPF-free and consitently
       behaving apps, these would better be fixed. With
       string params ISNIL() is either superfluous or simply
       don't protect agains GPFs, for rest of the cases it
       either causes unexpected defaults (zero), or simply
       superfluous for the rest of the cases. IOW: Avoid it,
       use HB_ISNUM(), HB_ISCHAR() / parcx() instead.
