A command name and parameters make up each command. A command name usually consists of a verb, or action, followed by a noun or phrase that identifies the receiver of the action. Abbreviated words, usually to three letters, make up the command name. This reduces the amount of typing that is required to enter the command. For example, one of the CL commands is the Send Message command. You would use the command that is named SNDMSG to send a message from a user to a message queue.
The parameters used in CL commands are keyword parameters. The keyword, usually abbreviated the same way as commands, identifies the purpose of the parameter. However, when commands are entered, some keywords may be omitted by specifying the parameters in a certain order (positional specification).
