The COBOL standard is set by ANSI (the American National Standards Institute). The standard defines the syntax and keywords of the COBOL programming language. The ANSI COBOL Standard has a long history:
ANSI COBOL 2014 | Made many features optional. Replaced portable arthmetic results with IEEE 754 data types. Added dynamic capacity tables. |
ANSI COBOL 2002 | Introduced Object Oriented COBOL (OO COBOL) plus a large list of features such as: free-form code, recursion, booleans, pointers and SCREEN SECTION. |
ANSI COBOL 85 | Added features: scope terminators (END-IF, END-PERFORM, etc.), CONTINUE statement, EVALUATE statement and inline PERFORM loop. Many other features were deprecated. |
ANSI COBOL 74 | Added the DELETE statement and Segmentation Module. Dropped the NOTE and EXAMINE statements. IBM COBOL 1.0 is based on ANSI COBOL-74. |
ANSI COBOL 68 | Introduced COBOL-68 as the first COBOL standard. |
COBOL 60 | Released first COBOL version, but it is not yet a standard. |
