An initialized set is empty, i.e. contains no members. All set manipulation routines make use of dynamic storage, which must be initialized before use. See 'dsinit' for further information. Note that all set manipulation routines have long names. To avoid unique name conflicts with other routines, any Ratfor program using the set routines should include the following statement: | include "=src=/lib/math/swtmlb_link.r.i" _I_m_p_l_e_m_e_n_t_a_t_i_o_n 'Set_init' simply clears all elements of the bit vector por- tion of the data structure addressed by its first argument. _S_e_e _A_l_s_o other set routines ('set_?*') (4) set_init (4) - 1 - set_init (4)
