The program function keyboard is a group of keys called PFKs. They are located on or near the operator console keyboard. PFKs are used as a shortcut for entering commands. Some PFKs have commands defined for them at IPL. The definitions might be those in a PFK table that your system programmer assigned to the console, or the PFKs might have the defaults assigned by IBM®. You can redefine the PFK commands; see “Defining PFKs using PFK Tables” and Defining PFKs using the CONTROL command in Defining and changing console characteristics.
Each PFK can be either conversational or nonconversational. The commands associated with a conversational PFK appear in the entry area one at a time when you press the key. You can change them before entering them. Commands associated with a nonconversational PFK are entered immediately when you press the key.
