xref (1) --- Ratfor cross reference generator 08/27/84 | _U_s_a_g_e xref { -{b | i | l | p | u} } { } _D_e_s_c_r_i_p_t_i_o_n 'Xref' produces a cross referenced listing of a Ratfor program. The listing consists of the program text, with consecutively numbered lines, and an alphabetical concor- dance of the identifiers that occur in the program text. The program text is read from the concatenation of all the files specified as arguments. If there are none, standard input is used. Several command line options are available to control the operation of 'xref': | -b highlight keywords by boldfacing. Any Ratfor or Fortran keywords contained in the program text will be boldfaced (by overstriking) in the listing. If the listing is to be printed on a line printer, the output should be filtered through 'os' to convert the over- strikes into multiple lines with Fortran forms control. | -i process 'include' statements. Any 'include' statements encountered in the program text will be expanded in- line. The included lines will be numbered consecutively as if they appeared in the primary input file. | -l include literals in the concordance. Any numeric literals that appear in the program text will be included with the identifiers in the concordance. | -p format listing for printing. A formfeed will be generated following the listing of each input file. Output under this option is suitable for piping into 'pr'. | -u highlight keywords by underlining. Any Ratfor or Fortran keywords contained in the program text will be underlined (by overstriking) in the listing. If the listing is to be printed on a line printer, the output should be filtered through 'os' to convert the over- strikes into multiple lines with Fortran forms control. _E_x_a_m_p_l_e_s rfprog.r> xref xref -pu prog1 prog2 prog3 | print | os >/dev/lps/f xref (1) - 1 - xref (1) xref (1) --- Ratfor cross reference generator 08/27/84 _S_e_e _A_l_s_o os (1), pr (1), rp (1) xref (1) - 2 - xref (1)
