INDEX(3F)                                                            INDEX(3F)



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
       Index  (rindex) returns the index of the first (last) occurrence of the
       substring substr in string, or zero if it does not occur.  Index is  an
       f77 intrinsic function; rindex is a library routine.

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