Comments:

This function does not automatically update the screen; it merely defines the backdrop character and attribute to Panels. You must redraw the screen using PF-Redraw-Screen before the changed backdrop character and attribute are displayed.

Example:

This example makes the backdrop character an asterisk. The backdrop attribute is set to a red foreground on a blue background.

     move "*" to ppb-fill-character.
     move x"14" to ppb-fill-attribute.
     move pf-set-screen-backdrop to ppb-function.
     call "PANELS" using panels-parameter-block.
     if ppb-status not = zero
*        (code to abort)
