  This function is the primary interface to the internal\r

                  value of the HII form package that is required\r
                  to be displayed.\r
\r
  @param HandleCount  The number of handles in the array\r
                      specified by Handle.\r
\r
  @param SingleUse  If FALSE, the browser operates as a standard\r
                    forms processor and exits only when\r
