I have sas/stat and sas foundations but not sas/iml
I'm trying to find the area for an irregular polygon. My dataset consists of many points but the example below contains just 8 coordinates.
Is there a good algorithm available for doing this? Ideally generalizing it so that it can apply to potentially 100s of points.

This paper may provide a starting point. http://www.caloxy.com/papers/52-DataX_gis_poster.pdf
It has a few pages worth of code to do this and find "interior" points. The code dates from the 80's and doesn't use proc gis or similar.
Understanding the code may be a learning exercise.
