IBM 1400 series
The IBM 1400 series are second-generation (transistor) mid-range business decimal computers that IBM marketed in the early 1960s. The computers were offered to replace tabulating machines like the IBM 407. The 1400-series machines stored infor ...

z/VSE), and
x86 (

At the height of COBOL usage in the 1960s through 1980s, the IBM COBOL product was the most important of any industry COBOL
compiler
In computing, a compiler is a computer program that Translator (computing), translates computer code written in one programming language (the ''source'' language) into another language (the ''target'' language). The name "compiler" is primaril ...
s. 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. 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.
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.
The Capex Optimizer became a quite successful product.
Although the IBM COBOL Compiler Family web site
[
] only mentions AIX, Linux, and z/OS, IBM still offers COBOL on z/VM and z/VSE.
