History[edit]
Clipper was created by Nantucket Corporation, a company that was started in 1984 by Barry ReBell (management) and Brian Russell (technical). In 1992, the company was sold to Computer Associates for 190 million dollars and the product was renamed to CA-Clipper.[1][2]

Clipper was created as a replacement programming language for Ashton Tate's dBASE III, a very popular database language at the time. The advantage of Clipper over dBASE was that it could be compiled[3] and executed under MS-DOS as a standalone application. In the years between 1985 and 1992 millions of Clipper applications were built, typically for small businesses dealing with databases concerning many aspects of client management and inventory management. For many smaller businesses, having a Clipper application designed to their specific needs was their first experience with software development. Also a lot of applications for banking and insurance companies were developed, here especially in those cases where the application was considered too small to be developed and run on traditional mainframes. In these environments Clipper also served as a front end for existing mainframe applications.[4]
As the product matured, it remained a DOS tool for many years, but added elements of the C programming language and Pascal programming language, as well as OOP, and the code-block, billed as 'dBasecompilers'

Clipper tools[edit]
Additional to a standard clipper library, a notable additional library named Clipper Tools were developed by CA after beginning a Clipper production. Three versions of this library were manufactured. All of them associated with a 5st Clippers version. This library became a de facto standard between a Clipper's clones, such as xHarbour, and it was also cloned for a number of Clipper clones manufacturers.

As a technical marketing ploy, the p-code was wrapped into object code (linkable .obj files) which gave the impression that it was compiled to native code.
