Cell-Color
This property allows you to set or retrieve the color of the cell identified by the X and Y properties. Foreground and background color values are combined and therefore RGB colors are not supported. See "Color management" for further details. When this property is set to zero, the cell inherits the row color.
 
Example - Modify a grid to set the background color of a cell
procedure division.
