Mal was anderes als Java. Die Programmiersprache COBOL<\/a> l\u00e4uft auch auf dem Raspberry Pi. Es gibt eine kostenlose Version, GnuCobol<\/a> das in 5 Minuten installiert werden kann. <\/p>\n

\r\nsudo apt-get update\r\nsudo apt-get upgrade\r\nsudo apt-get install open-cobol<\/pre>\n
Es wird die Version 1.1.0 von GnuCobol (OpenCobol<\/a>) installiert. Dass kann man leicht auf der Konsole testen mit:<\/p>\n
cobc -V<\/pre>\n
So, nun wollen wir wie \u00fcblich erst einmal ein erstes COBOL Programm compilieren. Dazu erstellen wir die hello.cob<\/strong> Datei mit diesem Inhalt:<\/p>\n
000100* hallo.cob GnuCobol Beispiel\r\n000200 IDENTIFICATION DIVISION.\r\n000300 PROGRAM-ID. hallo.\r\n000400 PROCEDURE DIVISION.\r\n000500     DISPLAY \"Hallo Welt\".\r\n000600     STOP RUN.<\/pre>\n
 <\/p>\n
Dies COBOL Datei compilieren wir mit diesem Aufruf:<\/p>\n
cobc -x hallo.cob<\/pre>\n
Nach ein paar Sekunden ist die Datei compiliert. Die hallo<\/strong> Datei liegt nun im gleichen Verzeichnis und kann nun wie folgt ausgef\u00fchrt werden:<\/p>\n
.\/hallo<\/pre>\n
Wir erhalten das programmierte Ergebnis:<\/p>\n
Hallo Welt<\/pre>\n
Weitere Optionen des Cobol-Compilers gibt es mit cobc -h<\/strong><\/p>\n
