| 17 | + | Assignfile(txtDatei, '/etc/issue'); // weist txtDatei die Datei zu | |
| 18 | + | reset(txtDatei); // oeffnet die Datei zum lesen | |
| 19 | + | readln(txtDatei, Result); // liest die erste Zeile | |
| 20 | + | Closefile(txtDatei); // schliesst die Datei | |
| 21 | + | end; | |

| 34 | + | ||
| 35 | + | // Wandelt alle Grossbuchstaben in Kleinbuchstaben um | |
| 36 | + | strDistribution := LowerCase(strDistribution); | |
