SUBROUTINE OPLOOK (NDICT, DICTRY, ALPHA, KEY, ENTRY) |
| 1398 |
C |
| 1399 |
C |
| 1400 |
C Description and usage: |
| 1401 |
C |
| 1402 |
C Performs dictionary lookups. A pointer is returned if a |
| 1403 |
C match is found between the input key and the corresponding |
| 1404 |
C initial characters of one of the elements of the dictionary. |
| 1405 |
C If a "synonym" has been provided for an entry, the search is |
| 1406 |
C continued until a match to a primary dictionary entry is found. |
| 1407 |
C Cases of no match, or multiple matches, are also provided for. |
| 1408 |
C |
| 1409 |
C Dictionary entries must be left-justified, and may be alphabetized |
| 1410 |
C for faster searches. Secondary entries, if any, are composed of |
| 1411 |
C two words separated by one or more characters such as blank, tab, |
| 1412 |
C comma, colon, or equal sign which are treated as non-significant |
| 1413 |
C by OPSCAN. The first entry of each such pair serves as a synonym |
| 1414 |
C for the second, more fundamental keyword. |
| 1415 |
C |
| 1416 |
C The ordered search stops after the section of the dictionary |
| 1417 |
C having the same first letters as the key has been checked, or |
| 1418 |
C after a specified number of entries have been examined. A special |
| 1419 |
C dictionary entry, the vertical bar '|', will also terminate the |
| 1420 |
C search. This will speed things up if an appropriate dictionary |
| 1421 |
C length parameter cannot be determined. Both types of search are |
| 1422 |
C sequential. See "Notes" below for some suggestions if efficiency |
| 1423 |
C is an issue. |
| 1424 |
C |
| 1425 |
C |
| 1426 |
C Parameters: |
| 1427 |
C |
| 1428 |
C Name Dimension Type I/O/S Description |
| 1429 |
C NDICT I I Number of dictionary entries to be |
| 1430 |
C examined. |
| 1431 |
C DICTRY NDICT C I Array of dictionary entries, |
| 1432 |
C left-justified in their fields. |
| 1433 |
C May be alphabetized for efficiency, |
| 1434 |
C in which case ALPHA should be |
| 1435 |
C .TRUE. Entries with synonyms are |
| 1436 |
C of the form |
| 1437 |
C 'ENTRY : SYNONYM', where 'SYNONYM' |
| 1438 |
C is a more fundamental entry in the |
| 1439 |
C same dictionary. NOTE: Don't build |
| 1440 |
C "circular" dictionaries! |
| 1441 |
C ALPHA L I Indicates whether the dictionary |
| 1442 |
C is in alphabetical order, in which |
| 1443 |
C case the search can be terminated |
| 1444 |
C sooner. |
| 1445 |
C KEY C I/O String to be compared against the |
| 1446 |
C dictionary. Abbreviations are OK |
| 1447 |
C if they correspond to a unique |
| 1448 |
C entry in the dictionary. KEY is |
| 1449 |
C replaced on termination by its most |
| 1450 |
C fundamental equivalent dictionary |
| 1451 |
C entry (uppercase, left-justified) |
| 1452 |
C if a match was found. |
| 1453 |
C ENTRY I O Dictionary pointer. If > 0, it |
| 1454 |
C indicates which entry matched KEY. |
| 1455 |
C In case of trouble, a negative |
| 1456 |
C value means that a UNIQUE match |
| 1457 |
C was not found - the absolute value |
| 1458 |
C of ENTRY points to the second |
| 1459 |
C dictionary entry that matched KEY. |
| 1460 |
C Zero means that NO match could be |
| 1461 |
C found. ENTRY always refers to the |
| 1462 |
C last search performed - |
| 1463 |
C in searching a chain of synonyms, |
| 1464 |
C a non-positive value will be |
| 1465 |
C returned if there is any break, |
| 1466 |
C even if the original input key |
| 1467 |
C was found. |

C |
| 1475 |
C |
| 1476 |
C Environment: Digital VAX-11/780 VMS FORTRAN (FORTRAN 77). |
| 1477 |
C Appears to satisfy the ANSI Fortran 77 standard. |

C |
| 1479 |
C |
| 1480 |
C Notes: |
| 1481 |
C |
| 1482 |
C (1) IMPLICIT NONE is non-standard. (Has been commented out.) |
| 1483 |
C |
| 1484 |
C (2) We have assumed that the dictionary is not too big. If |
| 1485 |
C many searches are to be done or if the dictionary has more |
| 1486 |
C than a dozen or so entries, it may be advantageous to build |
| 1487 |
C an index array of pointers to the beginning of the section |
| 1488 |
C of the dictionary containing each letter, then pass in the |
| 1489 |
C portion of the dictionary beginning with DICTRY (INDEX). |
| 1490 |
C (This won't generally work for dictionaries with synonyms.) |
| 1491 |
C For very large problems, a completely different approach may |
| 1492 |
C be advisable, e.g. a binary search for ordered dictionaries. |
| 1493 |
C |
| 1494 |
C (3) OPLOOK is case sensitive. In most applications it will be |
| 1495 |
C necessary to use an uppercase dictionary, and to convert the |
| 1496 |
C input key to uppercase before calling OPLOOK. Companion |
| 1497 |
C routines OPTOKN and PAIRS, available from the author, already |
| 1498 |
C take care of this. |
| 1499 |
C |
| 1500 |
C (4) The key need not be left-justified. Any leading (or |
| 1501 |
C trailing) characters which are "non-significant" to OPSCAN |
| 1502 |
C will be ignored. These include blanks, horizontal tabs, |
| 1503 |
C commas, colons, and equal signs. See OPSCAN for details. |
| 1504 |
C |
| 1505 |
C (5) The ASCII collating sequence for character data is assumed. |
| 1506 |
C (N.B. This means the numerals precede the alphabet, unlike |
| 1507 |
C common practice!) This should not cause trouble on EBCDIC |
| 1508 |
C machines if DICTRY just contains alphabetic keywords. |
| 1509 |
C Otherwise it may be necessary to use the FORTRAN lexical |
| 1510 |
C library routines to force use of the ASCII sequence. |
| 1511 |
C |
| 1512 |
C (6) Parameter NUMSIG sets a limit on the length of significant |
| 1513 |
C dictionary entries. Special applications may require that |
| 1514 |
C this be increased. (It is 16 in the present version.) |
| 1515 |
C |
| 1516 |
C (7) No protection against "circular" dictionaries is provided: |
| 1517 |
C don't claim that A is B, and that B is A. All synonym chains |
| 1518 |
C must terminate! Other potential errors not checked for |
| 1519 |
C include duplicate or mis-ordered entries. |
| 1520 |
C |
| 1521 |
C (8) The handling of ambiguities introduces some ambiguity: |
| 1522 |
C |
| 1523 |
C ALPHA = .TRUE. A potential problem, when one entry |
| 1524 |
C looks like an abbreviation for another |
| 1525 |
C (eg. does 'A' match 'A' or 'AB'?) was |
| 1526 |
C resolved by dropping out of the search |
| 1527 |
C immediately when an "exact" match is found. |
| 1528 |
C |
| 1529 |
C ALPHA = .FALSE. The programmer must ensure that the above |
| 1530 |
C situation does not arise: each dictionary |
| 1531 |
C entry must be recognizable, at least when |
| 1532 |
C specified to full length. Otherwise, the |
| 1533 |
C result of a search will depend on the |
| 1534 |
C order of entries. |

************************************************************************ |
| 1717 |
* Description and usage: |
| 1718 |
* |
| 1719 |
* A simple(-minded) test for numeric data is implemented by |
| 1720 |
* searching an input string for legitimate characters: |
| 1721 |
* digits 0 to 9, D, E, -, + and . |
| 1722 |
* Insurance is provided by requiring that a numeric string |
| 1723 |
* have at least one digit, at most one D, E or . |
| 1724 |
* and at most two -s or +s. Note that a few ambiguities remain: |
| 1725 |
* |
| 1726 |
* (a) A string might have the form of numeric data but be |
| 1727 |
* intended as text. No general test can hope to detect |
| 1728 |
* such cases. |
| 1729 |
* |
| 1730 |
* (b) There is no check for correctness of the data format. |
| 1731 |
* For example a meaningless string such as 'E1.+2-' |
| 1732 |
* will be accepted as numeric. |
| 1733 |
* |
| 1734 |
* Despite these weaknesses, the method should work in the |
| 1735 |
* majority of cases. |

* |
| 1748 |
* |
| 1749 |
* Notes: |
| 1750 |
* |
| 1751 |
* (1) It is assumed that STRING is a token extracted by |
| 1752 |
* OPTOKN, which will have converted any lower-case |
| 1753 |
* characters to upper-case. |
| 1754 |
* |
| 1755 |
* (2) OPTOKN pads STRING with blanks, so that a genuine |
| 1756 |
* number is of the form '1234 '. |
| 1757 |
* Hence, the scan of STRING stops at the first blank. |
| 1758 |
* |
| 1759 |
* (3) COMPLEX data with parentheses will not look numeric. |

C |

C |
| 1816 |
C Description and usage: |
| 1817 |
C |
| 1818 |
C Looks for non-blank fields ("tokens") in a string, where the |
| 1819 |
C fields are of arbitrary length, separated by blanks, tabs, commas, |
| 1820 |
C colons, or equal signs. The position of the end of the 1st token |
| 1821 |
C is also returned, so this routine may be conveniently used within |
| 1822 |
C a loop to process an entire line of text. |
| 1823 |
C |
| 1824 |
C The procedure examines a substring, STRING (FIRST : LAST), which |
| 1825 |
C may of course be the entire string (in which case just call OPSCAN |
| 1826 |
C with FIRST <= 1 and LAST >= LEN (STRING) ). The indices returned |
| 1827 |
C are relative to STRING itself, not the substring. |

| 1834 |
C scanned. |
| 1835 |
C FIRST I I/O Index of beginning of substring. |
| 1836 |
C If <= 1, the search begins with 1. |
| 1837 |
C Output is index of beginning of |
| 1838 |
C first non-blank field, or 0 if no |
| 1839 |
C token was found. |
| 1840 |
C LAST I I/O Index of end of substring. |
| 1841 |
C If >= LEN (STRING), the search |
| 1842 |
C begins with LEN (STRING). Output |
| 1843 |
C is index of end of last non-blank |
| 1844 |
C field, or 0 if no token was found. |
| 1845 |
C MARK I O Points to end of first non-blank |
| 1846 |
C field in the specified substring. |
| 1847 |
C Set to 0 if no token was found. |

C Environment: Digital VAX-11/780 VMS FORTRAN (FORTRAN 77). |
| 1851 |
C ANSI Fortran 77, except for the tab character HT. |
| 1852 |
C |
| 1853 |
C Notes: |
| 1854 |
C |
| 1855 |
C (1) IMPLICIT NONE is non-standard. Constant HT (Tab) is defined |
| 1856 |
C in a non-standard way: the CHAR function is not permitted |
| 1857 |
C in a PARAMETER declaration (OK on VAX, though). For Absoft |
| 1858 |
C FORTRAN 77 on 68000 machines, use HT = 9. In other cases, it |
| 1859 |
C may be best to declare HT as a variable and assign |
| 1860 |
C HT = CHAR(9) on ASCII machines, or CHAR(5) for EBCDIC. |
| 1861 |
C |
| 1862 |
C (2) The pseudo-recursive structure was chosen for fun. It is |
| 1863 |
C equivalent to three DO loops with embedded GO TOs in sequence. |
| 1864 |
C |
| 1865 |
C (3) The variety of separators recognized limits the usefulness of |
| 1866 |
C this routine somewhat. The intent is to facilitate handling |
| 1867 |
C such tokens as keywords or numerical values. In other |
| 1868 |
C applications, it may be necessary for ALL printing characters |
| 1869 |
C to be significant. A simple modification to statement |
| 1870 |
C function SOLID will do the trick. |

C Description and usage: |
| 1975 |
C |
| 1976 |
C An aid to parsing input data. The individual "tokens" in a |
| 1977 |
C character string are isolated, converted to uppercase, and stored |
| 1978 |
C in an array. Here, a token is a group of significant, contiguous |

C characters. The following are NON-significant, and hence may |
| 1980 |
C serve as separators: blanks, horizontal tabs, commas, colons, |
| 1981 |
C and equal signs. See OPSCAN for details. Processing continues |
| 1982 |
C until the requested number of tokens have been found or the end |

C |
| 2099 |
C ACRONYM: UPper CASE |
| 2100 |
C |
| 2101 |
C PURPOSE: This subroutine changes all lower case letters in the |
| 2102 |
C character string to upper case. |
| 2103 |
C |
| 2104 |
C METHOD: Each character in STRING is treated in turn. The intrinsic |
| 2105 |
C function INDEX effectively allows a table lookup, with |
| 2106 |
C the local strings LOW and UPP acting as two tables. |
| 2107 |
C This method avoids the use of CHAR and ICHAR, which appear |
| 2108 |
C be different on ASCII and EBCDIC machines. |
