Instructions
An instruction initiates an action. For example, ClrDraw is an instruction
that clears any drawn elements from a graph. Instructions cannot be
used in expressions. In general, the first letter of each instruction name
is uppercase. Some instructions take more than one argument, as
indicated by an open parenthesis ( ( ) at the end of the name. For
example, Circle( requires three arguments, Circle(X,Y,radius).
