| 21 | .SH DESCRIPTION | |
| 22 | .I Index | |
| 23 | .I (rindex) | |
| 24 | returns the index of the first (last) occurrence of the substring | |
| 25 | .I substr | |
| 26 | in | |
| 27 | .I string, | |
| 28 | or zero if it does not occur. | |
| 29 | .I Index | |
| 30 | is an f77 intrinsic function; | |
| 31 | .I rindex | |
| 32 | is a library routine. | |
| 33 | .PP | |
| 34 | .I Lnblnk | |
| 35 | returns the index of the last non-blank character in | |
| 36 | .I string. | |
| 37 | This is useful since all f77 character objects are fixed length, blank padded. | |
| 38 | Intrinsic function | |
| 39 | .I len | |
| 40 | returns the size of the character object argument. | |
