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.

Example:

FORMAT KD=ON
