IBM has offered the computer programming language COBOL on many platforms, starting with the IBM 1400 series and IBM 7000 series, continuing into the industry-dominant IBM System/360 and IBM System/370 mainframe systems, and then through Power Systems (AIX) and IBM Z (z/OS and z/VSE).
At the height of COBOL usage in the 1960s through 1980s, the IBM COBOL product was the most important of any industry COBOL compilers. In his popular textbook A Simplified Guide to Structured COBOL Programming, Daniel D. McCracken tries to make the treatment general for any machine and compiler, but when he gives details for a particular one, they are to the IBM COBOL compiler and for a System/370.[1] Similarly, another popular textbook of the time, Stern and Stern's Structured COBOL Programming, tries to present an implementation-independent explanation of the language, but the appendix giving the full syntax of the language is explicitly for IBM COBOL, with its extensions to the language highlighted.[2]
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 and z/OS, IBM still offers COBOL on z/VM and z/VSE.
