{ Note: The routines that convert from a string are defined
  to take a POleStr rather than a TBStr because no allocation is
  required, and this makes the routines a bit more generic.
  They may of course still be passed a TBStr as the strIn param. }

{ Any of the coersion functions that converts either from or to a string
  takes an additional lcid and dwFlags arguments. The lcid argument allows
  locale specific parsing to occur.  The dwFlags allow additional function
  specific condition to occur.  All function that accept the dwFlags argument
  can include either 0 or LOCALE_NOUSEROVERRIDE flag. In addition, the
  VarDateFromStr functions also accepts the VAR_TIMEVALUEONLY and
  VAR_DATEVALUEONLY flags }
