CLP = Control Language Programming Language.

Much of what we find in CLP programs are IBM Commands. [1] Also see CLP Coding Rules and CLP Commands.

As with many other languages, there are multiple versions in popular usage, such as CLP/400 and ILE-CLP.

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.

CLP Unique Commands

Some 400 Commands [2] can ONLY be executed from within a CLP program, not from Command Line. In other programming languages, these might be called OP CODES.

  • PGM (Program)
  • ENDPGM
  • DCL (Declare Variable)
  • IF
  • ELSE
  • DO
  • ENDDO
  • GOTO
