Control Language (CL) Concepts

Command names

Most command names consist of a combination of the verb and the object being acted on: (command = verb + object acted on). For example, you can create, delete, or display a library; so the verb abbreviations CRT, DLT, and DSP are joined to the abbreviation for library, LIB. The result is three commands that can operate on a library: CRTLIB, DLTLIB, and DSPLIB.

The conventions for naming the combination verb and object commands are as follows:

Some command names consist of the verb only, such as the MOV (Move) command, or an object only, such as the DATA (Data) command.

A few commands have an OS/400(R) command name, and can also be called using one or more alternate names that may be familiar to users of systems other than the OS/400 system. An alternate name is known as an alias, such as the name CD is an alias for the CHGCURDIR (Change Current Directory) command.
