27 | .SH DESCRIPTION | |
28 | .I Index | |
29 | .I (rindex) | |
30 | returns the index of the first (last) occurrence of the substring | |
31 | .I substr | |
32 | in | |
33 | .I string, | |
34 | or zero if it does not occur. | |
35 | .I Index | |
36 | is an f77 intrinsic function; | |
37 | .I rindex | |
38 | is a library routine. | |
39 | .PP | |
40 | .I Lnblnk | |
41 | returns the index of the last non-blank character in | |
42 | .I string. | |
43 | This is useful since all f77 character objects are fixed length, blank padded. | |
44 | Intrinsic function | |
45 | .I len | |
46 | returns the size of the character object argument. | |
