print #handle, "down"
This command is the opposite of UP.  This command reactivates the drawing process.  The pen must be DOWN to cause graphics to be displayed.

print #handle, "home"
This command centers the pen in the graphics window.

print #handle, "up"
This command lifts up the pen.  All GO or GOTO commands will now only move the pen to its new position without drawing.  Any other drawing commands will simply be ignored until the pen is put back down.

print #handle, "size S"
This command sets the size of the pen to S.  The default is 1.  This will affect the thickness of lines and figures plotted with most of the commands listed in this section.
