GnuCOBOL (formerly known as OpenCOBOL, and briefly as GNU Cobol) is a free implementation of the COBOL programming language that is part of the GNU project. GnuCOBOL translates the COBOL code into C and then compiles it using the native C compiler .
COBOL 2002 also introduced free-format code. Free-format code can be placed in any column of the file, as in newer programming languages. Comments are specified using *>, which can be placed anywhere and can also be used in fixed-format source code. Continuation lines are not present, and the >>PAGE directive replaces the / indicator.

Early versions supported IBM's DB2 database, 3270 'block mode' screens and generated COBOL code. In the intervening years the toolset has been expanded to support additional development techniques such as component-based development; creation of client/server and web applications and generation of C, Java and C#. In addition, other platforms ...
Use of IBM COBOL was so widespread that Capex Corporation, an independent software vendor, made a post-code generation phase object code optimizer for it. [3] The Capex Optimizer became a quite successful product. [4] Although the IBM COBOL Compiler Family web site [5] only mentions AIX, Linux, and z/OS, IBM still offers COBOL on z/VM and z/VSE.
McNeil designed the template COBOL programs and Christensen coded the macros to generate the actual COBOL programs. They created a system that could generate COBOL code from screen layouts created by users. The COBOL ran in IBM's TSO interactive environment and it allowed the users and engineers to test screen flow. When a user wanted a change ...
The table is stored in a file that can be produced by the IBM High-Level Assembler (HLASM), [18] IBM's COBOL compiler, [19] and IBM's PL/I compiler. [20] Microsoft Windows has available a symbol table [21] that is stored in a program database (.pdb) file. [22] Most Unix-like operating systems have available symbol table formats named stabs and ...

COBOL and PL/I also have a system-independent method of specifying printer controls. The compiler or run-time will translate these options into the appropriate control character. The compiler or run-time will translate these options into the appropriate control character.
