            _F_u_n_c_t_i_o_n

                 'Jdate'  is  used to determine the Julian date corresponding
                 to a given month, day,  and  year.   (For  example,  January
                 first  of  any  year  has Julian date 1; December 31st might
                 have Julian date 365 or 366, depending on whether the  given
                 year  is  a  leap  year or not.)  The function return is the
                 Julian date calculated.


            _I_m_p_l_e_m_e_n_t_a_t_i_o_n

                 'Jdate' simply adds up the number  of  days  in  all  months
                 before  the month given, then adds the number of days given.
                 If the year specified is a leap year, February is  given  29
                 days instead of the usual 28.
