There is +no restriction on the length of identifiers, and all the characters are +significant in deciding whether two identifiers are the same. +Identifiers fall into two different classes (called in the formal syntax +`identifier' and `IDENTIFIER') depending on whether their initial letter +is upper or lower case. + +Identifiers are used for three different purposes in Miranda - (i) as +variables, i.e. names for values (note that the names of functions are +also considered to be variables), (ii) as typenames, such as `bool' and +`char', and (iii) as constructors (see section on algebraic types). The +names of constructors must begin with an upper case letter, while +variables and typenames must begin with a lower case letter. + +Reserved words - the following are special symbols of the Miranda +language. + +_a_b_s_t_y_p_e _d_i_v _i_f _m_o_d _o_t_h_e_r_w_i_s_e _r_e_a_d_v_a_l_s _s_h_o_w _t_y_p_e _w_h_e_r_e _w_i_t_h + (10) + +These are often shown as underlined (or bold) in published documents, +but in programs they are typed as ordinary lower case words (which means +that these words cannot be used as identifiers). + +_P_r_e_d_e_f_i_n_e_d_ _i_d_e_n_t_i_f_i_e_r_s + +The following identifiers are normally* predefined and always in scope. +They constitute the `standard environment'.
