The Control Language (CL) is a scripting language originally created by IBM for the System/38 Control Program Facility [1] and later used in OS/400 (now known as IBM i). It bears a resemblance to the IBM Job Control Language and consists of a set of command objects (*CMD) used to invoke traditional programs or get help on what those programs do.
The true command is sometimes substituted with the very similar null command, [1] written as a single colon (:).The null command is built into the shell, and may therefore be more efficient if true is an external program (true is usually a shell built in function).

A command language is a language for job control in computing. [1] It is a domain-specific and interpreted language; common examples of a command language are shell or batch programming languages. These languages can be used directly at the command line, but can also automate tasks that would normally be performed manually at the command line.
If a script is invoked as an argument to the interpreting shell, it will be executed regardless of whether the user holds the execute permission for that script. Although Windows also specifies an execute permission, none of the Windows-specific shells block script execution if the permission has not been granted.
Shell variables, created using the set or @ statements, are internal to C shell. They are not passed to child processes. Shell variables can be either simple strings or arrays of strings. Some of the shell variables are predefined and used to control various internal C shell options, e.g., what should happen if a wildcard fails to match anything.
