COBOL stands for Common Business Oriented Language. It is a complete Programming Language and is most widely used for developing business applications. COBOL is a third-generation high-level language, procedure-oriented and machine-independent.
COBOL implementation is a superset of the ANSI and ISO COBOL standard as specified in ANSI X3.23-1974 (ISO 1989-1978), and of the current ANSI and ISO COBOL standard as specified in ANSI X3.23-1985 (IS 1989:1985), ANSI X3.23a-1989 (IS 1989:1985/AM1), and ANSI X3.23b-1993 (IS 1989:1985/AM2).Language extensions include:
- most of the more commonly used extensions of IBM O S/VS COBOL (Release 2.3 and later)
- most of the language constructs of IBM VS COBOL II (all releases), IBM DOS/VS COBOL and IBM SAA AD/Cycle COBOL/370
- X/Open conforming extensions
- extensions specific to this system.
Combinations of these extensions are permissible in program source. In addition a “flagging” option to identify the various language extensions in COBOL source programs ensures that programs can be verified as being valid for any given one of the language specifications.
