The CONSTELLATION command plots the main constellations stars in the FRAME area, using the current pen and marker. The marker size will scale acrording to the star magnitude. Options are available to draw lines between stars (to form classical constellation outlines) or plot the star names. See the corresponding section of language internal help for details.

Example - Figure [*] shows the plot resulting from the commands:
