NAME
     index, rindex, lnblnk, len - tell about character objects

SYNOPSIS
     (intrinsic) function index (string, substr)
     character*(*) string, substr

     integer function rindex (string, substr)
     character*(*) string, substr

     function lnblnk (string)
     character*(*) string

     (intrinsic) function len (string)
     character*(*) string

DESCRIPTION
     _I_n_d_e_x (_r_i_n_d_e_x) returns the index of the first (last)
     occurrence of the substring _s_u_b_s_t_r in _s_t_r_i_n_g, or zero if it
     does not occur.  _I_n_d_e_x is an f77 intrinsic function; _r_i_n_d_e_x
     is a library routine.

     _L_n_b_l_n_k returns the index of the last non-blank character in
     _s_t_r_i_n_g. This is useful since all f77 character objects are
     fixed length, blank padded.  Intrinsic function _l_e_n returns
     the size of the character object argument.
