Since then, responsibility for developing new COBOL standards has been assumed by the American National Standards Institute (ANSI). Interduction to CobolĬOBOL is a high-level programming language first developed by the CODASYL Committee (Conference on Data Systems Languages) in 1960. This book is written based on IBM COBOL for OS/390 V2R2. First COBOL compiler was released by December 1959. History of Cobol.ĭeveloped by 1959 by a group called COnference on Data Systems Language (CODASYL). Application program development processĦ.
