COBOL programs are used globally in governments and businesses and are running on diverse operating systems such as z/OS, z/VSE, VME, Unix, NonStop OS, OpenVMS and Windows. In 1997, the Gartner Group reported that 80% of the world's business ran on COBOL with over 200 billion lines of code [c] and 5 billion lines more being written annually. [114]
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 ...

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 embedded SQL statements are parsed by an embedded SQL preprocessor and replaced by host-language calls to a code library. The output from the preprocessor is then compiled by the host compiler. This allows programmers to embed SQL statements in programs written in any number of languages such as C/C++, COBOL and Fortran.
– 5 stars Bill S. from St. Louis, Missouri, writes, "We were passing through Green Bay on the way to Door County and decided to stay a night in town. We had a room about two blocks away.
It is used in character data on IBM mainframes by languages such as COBOL, PL/I, and RPG. [1] Its purpose is to save a character that would otherwise be used by the sign digit. [2] The code is derived from the Hollerith Punched Card Code, where both a digit and a sign can be entered in the same card column. It is called an overpunch because the ...
