# KD - Key Definition

This session parameter is used to display the names assigned to the PF keys (see the `SET KEY` statement).

Possible settings | `ON` | The names assigned to the PF keys are displayed.
`OFF` | The names assigned to the PF keys are not displayed.
Default setting | `OFF` |
Specification within session | yes |
Applicable statements | `FORMAT` |
Applicable command | none |

Notes:

1. The PF key assignment information will always be displayed automatically in the two bottom lines of the physical screen with any output created by the `INPUT`, `WRITE`, `DISPLAY`, and `PRINT` statement.
2. As the key assignment display requires two lines, the logical page size (see the session parameter `PS`) must be reduced by two.
3. In case of graphical user interfaces: If PF keys are defined, they are always displayed, regardless of the setting of this parameter. If no PF keys are defined, this parameter can be used to switch on/off the display of the ENTER key.

#### Example:

    FORMAT KD=ON
