GOFF
The GOFF (Generalized Object File Format) specification was developed for the IBM zSystem Mainframe computer to supersede the IBM OS/360 Object File Format to compensate for weaknesses in the older format.〔John R. Ehrman, ''How the Linkage Editor Works: A Tutorial on Object/Load Modules, Link Editors, Loaders, and What They Do for (and to) You'', IBM Silicon Valley (Santa Teresa) Laboratory, San Jose, 1994, 2001 ftp://ftp.boulder.ibm.com/software/websphere/awdtools/hlasm/s8169a.pdf (Retrieved July 29, 2013)〕
==Background==
The original IBM OS/360 Object File Format was developed in 1964 for the new IBM System/360 mainframe computer. The format was also used by makers of plug compatible and workalike mainframes, including the Univac 90/60, 90/70 and 90/80 and Fujitsu B2800. The format was expanded to add symbolic records and expanded information about modules, plus support for procedures and functions with names longer than 8 characters. While this helped, it did not provide for the enhanced information necessary for today's more complicated programming languages and more advanced features such as objects, properties and methods, Unicode support, and virtual methods (a procedure in an object that is not known which procedure is invoked until the program runs, because a later definition of a procedure with the same name in a descendant object replaces the original procedure in the ancestor object).
The GOFF object file format was developed by IBM approximately in 1995〔The earliest mention of this format was in the introductory information about the new High Level Assembler, " IBM High Level Assembler for MVS & VM & VSE Release 2 Presentation Guide December 1995, SG24-3910-01" Available at http://www.redbooks.ibm.com/redbooks/pdfs/sg243910.pdf (Retrieved November 13, 2015). 〕 as a means to overcome these problems.〔''OS/MVS Program Management: Advanced Facilities'', SA22-7644-07, Eighth Edition, IBM, Poukeepsie, NY,Eighth Edition, September 2007 http://publibz.boulder.ibm.com/epubs/pdf/iea2b270.pdf (Retrieved August 9, 2013)〕 Note that the OS/360 Object File Format was simply superseded by the GOFF format, it was not deprecated, and is still in use by assemblers and language compilers where the language can withstand the limitations of the older format.
Note that this article will use the term "module" to refer to any name or equivalent symbol, which is used to provide an identifier for a piece of code or data external to the scope to which it is referenced. A module may refer to a subroutine, a function, a method or property of an object or class, or any other named routine or identifier external to that particular scope referencing the external name.
