+// The Clear Screen command clears the screen using the current background colour.
+// This command brings some of the settings back to default; such as,
+//  Transparency turned OFF
+//  Outline colour set to BLACK
+//  Opacity set to OPAQUE
+//  Pen set to OUTLINE
+//  Line patterns set to OFF
+//  Right text margin set to full width
+//  Text magnifications set to 1
+//  All origins set to 0:0
+// The alternative to maintain settings and clear screen is 
+// to draw a filled rectangle with the required background colour.
