Use PF-Get-Panel-Info if you know the handle of a panel but want to return information about its appearance.

Example:

This example identifies which panel is at line 4, column 6 (where 0,0 is the top left-hand corner of the screen).

     move 3 to ppb-panel-start-row.
     move 5 to ppb-panel-start-column.
     move pf-get-panel-at-position to ppb-function.
     call "PANELS" using panels-parameter-block.
