Clipper is an xBase compiler that implements a variant of the xBase computer programming language. It is used to create or extend software programs that originally ran usually on DOS. Although it is a powerful general-purpose programming language, it was used mainly to create database business programs.

One major dBase feature not implemented in Clipper is the dot-prompt (. prompt) interactive command set,^[1] which was an important part of the original dBase implementation.

Clipper, from Nantucket Corp and later Computer Associates, started out as a native code compiler for dBase III databases, and later evolved.^[2]
