Commands

This defines a command and provides information about how commands are named, the parts of a command, and command documentation. A control language (CL) command is a single control language statement.

• Command names
  The command name identifies the function that will be performed by the program that is called when the command is run. Most command names consist of a combination of a verb (or, action) followed by a noun or phrase that identifies the receiver of the action (or object being acted on): (command = verb + object acted on).
• Command parts
  The parts of a command include a command label (optional), a command name (mnemonic), and one or more parameters. The parameter includes a keyword and a value.
• Command definition parts
  Command definition allows system users to create additional commands to meet specific application needs. These commands are similar to the system commands.
• Command coding rules
  This section contains a summary of general information needed to properly code CL commands.
• Command information and documentation
  IBM^® provides documentation for i5/OS™ commands. In addition, you can write documentation for your own commands.
• Commands operating on i5/OS objects
  Each of the i5/OS™ object types has a set of commands that operates on that object type.
• Commands operating on multiple objects
  In addition to the commands that operate on single object types, there are commands that operate on several object types. These commands are more powerful because they can operate on several objects of different types at the same time.
