set "the points" of the polygon.
The "points" is a list of coordinate pairs x,y on separate lines.
e.g. to create a graphic & draw a square:

create graphic "Box"
set the style of graphic "Box" to "polygon"
set the points of graphic "Box" to "50,50" & cr & "50,100" & cr & \
       	"100,100" & cr & "100,50" & cr & "50,50"

set the opaque of graphic "What" to false

Exactly the same way as for a polygon, just use a different set of 
points. You can set the style to "line" or "polygon". It doesn't seem 
to matter much. If you use line, remember to put it inside quotes or 
you'll get an error.

This is a basically unsolved problem. Rev just uses a lookup table to 
get color names vs RGB values. Unfortunately, when you then query the 
color of something that was set using a name, it returns the name and 
not the RGB values.
If you want to find the complete list, open up the Application Overview 
and turn on Revolution UI stacks in list. Find revColors.rev and go to 
the only card in the only stack. Have a look at the properties and go 
to the Custom tab, then turn on "Show Revolution UI custom properties". 
The cRevColorTranslation property gives you all the names & RGB 
equivalents.

I'll leave this one to the array experts on this list...
