       _e_v_e_n_t          Points to the XXEEvveenntt, which  triggered  the
                      callback.

       _d_o_i_t           Indicates   whether  the  offending  action
                      should be performed. Setting this field  of
                      the  callback structure to FFaallssee denies the
                      action.

       _c_u_r_r_I_n_s_e_r_t     Specifies  the  current  position  of   the
                      insert cursor.

                      Indicates  the  position  at which the user
                      attempts to position the cursor.

       _s_t_a_r_t_P_o_s       Indicates the starting position of the text
                      to     modify.    If    the    reason    is
                      XXmmCCRR__MMOOVVIINNGG__IINNSSEERRTT__CCUURRSSOORR this value is the
                      same as ccuurrrrIInnsseerrtt.

       _e_n_d_P_o_s         Specifies  the  ending position of the text
                      to  modify.  If  no  text  is  replaced  or
                      deleted, then the value will be the same as
                      ssttaarrttPPooss.      If     the     reason     is
                      XXmmCCRR__MMOODDIIFFYYIINNGG__TTEEXXTT__VVAALLUUEE this value is the
                      same as _c_u_r_r_I_n_s_e_r_t.

       _t_e_x_t           Holds the address of a  structure  of  type
                      XXmmTTeexxttBBlloocckkRReecc   which  holds  the  textual
                      information to be inserted.

       The following table describes the reasons why the individ-
       ual verification callback structure fields are valid.

       _r_e_a_s_o_n         Indicates the reason why the  callback  was
                      activated. This is XXmmCCRR__SSOORRTTIINNGG.

       _e_v_e_n_t          Contains  always NNUULLLL and is just there for
                      compatibility reasons.

       _o_p_e_r_a_t_i_o_n      Indicates the operation to  carry  out  and
                      can   be   either   XXmmOOPP__IINNIITT,XXmmOOPP__DDOONNEE  or
                      XXmmOOPP__CCOOMMPPAARREE.

                      to  a  suitable  representation  of the new

                      the list ( XXmmOOPP__CCOOMMPPAARREE) the field contains
                      the  address  of  an item in the list which
                      should be compared against the new item (as
                      remembered in _i_t_e_m___i_n_t_e_r_n_a_l).

       _r_e_s_u_l_t         When comparing an item (out of the list) in
                      _i_t_e_m with the new item  (as  remembered  in
                      _i_t_e_m___i_n_t_e_r_n_a_l)  the result has to be stored
                      into this structure's field.
