| 3 | + | Dieses Beispiel prüft, ob das Jahr ein (christliches) Schaltjahr ab dem Jahr 1582 ist. | |
| 4 | + | ||
| 5 | + | Alternativ gibt es dazu in der Unit Sysutils die Funktion leap year (leap year = Schaltjahr). | |
| 6 | + | ||
| 7 | + | ``` pascal | |
| 8 | + | function funIstSchaltjahr(wrdJahr: word): integer; | |
| 9 | + | const | |
| 10 | + | conKalenderumstellung = 1583; | |
| 11 | + | conFehler = -1; | |
| 12 | + | conFalsch = 0; | |
| 13 | + | conWahr = 1; | |
| 14 | + | ||
| 15 | + | begin | |
| 16 | + | ||
| 17 | + | Result := conFehler; | |
| 18 | + | // Prüft auf die Richtigkeit des Kalenderjahres | |
| 19 | + | if wrdJahr < conKalenderumstellung then | |
| 20 | + | exit; | |
| 21 | + | ||
| 22 | + | Result := conFalsch; | |
| 23 | + | ||
| 24 | + | if (wrdJahr mod 4) = 0 then | |
| 25 | + | Result := conWahr; | |
| 26 | + | if (wrdJahr mod 100) = 0 then | |
| 27 | + | Result := 0; | |
| 28 | + | if (wrdJahr mod 400) = 0 then | |
| 29 | + | Result := conWahr; | |
| 30 | + | ||
| 31 | + | end; | |
