Dear Lynn,
I apologize for not being more explicit. In my example x is just a dummy variable, i.e., a variable I created to exemplify the procedure you were looking for. In your case, x should be created by yourself according to your needs, assigning value 0 to polygons you want to represent as "white", and value 1 to those you want to represent as "green". For instance, suppose your dataset includes 10 regions; regions 1, 3, 6, 8 are "white" (value 0), while the remaining regions are "green" (value 1). To create the new variable x, you might run the following command:

. generate x = 1 - inlist(id,1,3,6,8)

where -id- is an existing variable that uniquely identifies regions.
Best wishes,
Maurizio
