To make these in scope in another script, the +latter will contain the directive + %_i_n_c_l_u_d_e "mylib" + +This can come anywhere in the script (there is for example no +requirement that %_i_n_c_l_u_d_e directives come at the front) but must be at +top level - you may not place a %_i_n_c_l_u_d_e directive inside a _w_h_e_r_e +clause. The subject of a %_i_n_c_l_u_d_e directive may itself contain %_i_n_c_l_u_d_e +directives, and so on (to any reasonable depth). + +By default, the names `exported' from an included script are all those +defined in it at top level, but not those of subsidiary %_i_n_c_l_u_d_e's. +This can be modified by placing a `%_e_x_p_o_r_t' directive in the included +script. For a discussion of this and other ways of modifying the effect +of %_i_n_c_l_u_d_e see the manual section giving a detailed account of the +library directives. + +If the filename in a _%_i_n_c_l_u_d_e directive is enclosed in angle brackets +instead of string quotes, this is understood to be a pathname relative +to the miralib directory. So for example putting in your script + %_i_n_c_l_u_d_e <ex/matrix> +brings into scope the definitions exported from the matrix package in +the Miranda examples directory `ex'. (*See note below.) + +Finally, note that that the relationship between includor and includee +is unsymmetrical. If file A %_i_n_c_l_u_d_e's file B, then the declarations of +B are visible to A, but not vice versa. + +There is a simpler (purely textual) directive + %_i_n_s_e_r_t "file" +which causes the contents of "file" to be substituted for the %_i_n_s_e_r_t +directive during lexical analysis. This can occur anywhere in a Miranda +script. See manual section on compiler directives. + +------------------------------------------------------------------------ +(*) Note to system administrators: an empty directory `local' is +provided under the miralib directory, in which you can place additional +libraries which you wish to make available to all Miranda users at your +site. + |
