put the screen of this stack into theScreen
put line theScreen of the screenRects into theStackScreenRect

From my memory of following the repo feed the screen of stack was undocumented until recently when Trevor documented it which probably means it is only documented in LC 8 so not sure what version it was introduced but it stands to reason it may have been introduced when the screenRects was...
