CLP
From MidrangeWiki
CLP = Control Language Programming Language
As with many other languages, there are multiple versions in popular usage, such as CLP/400 and CLP_ILE.
In some realities, this is comparable to software that is the "glue" connecting higher level language programs like RPG; data base files and their over-rides; screen and print "files" and their over-rides; and other objects with Menus ... typically when we take a menu option, we are launching a CLP program.
