Question: Information:  - Mainframe computers (colloquially referred to as "big iron") are computers used primarily by large organizations for critical applications, bulk data processing, such as census, industry and consumer statistics, enterprise resource planning, and transaction processing.  - In computer science, transaction processing is information processing that is divided into individual, indivisible operations called "transactions". Each transaction must succeed or fail as a complete unit; it can never be only partially complete.  - GnuCOBOL ( formerly OpenCOBOL , and for a short time known as GNU Cobol ) is a free implementation of the COBOL programming language . Originally designed by Keisuke Nishida , lead development was taken up by Roger While . Latest developments are now led by Simon Sobisch , Sergey Kashyrin and Ron Norman .  - COBOL (an acronym for "common business-oriented language") is a compiled English-like computer programming language designed for business use. It is imperative, procedural and, since 2002, object-oriented. COBOL is primarily used in business, finance, and administrative systems for companies and governments. COBOL is still widely used in legacy applications deployed on mainframe computers, such as large-scale batch and transaction processing jobs. But due to its declining popularity and the retirement of experienced COBOL programmers, programs are being migrated to new platforms, rewritten in modern languages or replaced with software packages. Most programming in COBOL is now purely to maintain existing applications.  - An acronym is a word or name formed as an abbreviation from the initial components in a phrase or a word, usually individual letters (as in "NATO" or "laser") and sometimes syllables (as in "Benelux").    Given the information above, choose from the list below the object entity that exhibits the relation 'instance of' with the subject 'gnucobol'.  Choices: - abbreviation  - acronym  - census  - computer  - data  - enterprise  - industry  - information  - object  - programming  - programming language  - scale  - science  - software  - statistics  - word
