What is KCML?

KCML is a fourth-generation programming language originally developed by Kerridge Computer Company and now maintained by Keyloop. It is widely used in the automotive retail and dealer management sector to build transaction-processing applications across a range of platforms.

KCML combines a structured procedural language with a rich set of built-in facilities for database access, screen and forms design, reporting, web integration, and inter-process communication — without requiring a separate application server or framework.
