RestScreen( [<nTop>] , [<nLeft>] , ; [<nBottom>], [<nRight>], <cScreen>) --> NIL
RestScreen() always returns the value NIL.
The screen function RestScreen() normally redisplays a segment of screen previously saved using the function SaveScreen(). The display can occur any place on the entire screen. When a saved screen segment is displayed at a new location, the new segment must have the same dimensions as the original.
Every second character in the character pairs comprising <cScreen>contains the color attribute for the visible character placed on the screen.
