Most CL commands have one or more parameters that specify the objects and values used to run the commands.
When a command is entered, the user supplies the command object name, the parameter keyword names, and the parameter values used by the command. The number of parameters specified depends upon the command. Some commands (like the DO (Do) command and the ENDBCHJOB (End Batch Job) command) have no parameters, and others have one or more.
In this topic, the word parameter usually refers to the combination of the parameter keyword and its value. For example, the Move Object (MOVOBJ) command has a parameter called OBJ that requires an object name to be specified. OBJ is the parameter keyword, and the name of the object is the value entered for the OBJ parameter.
