Dear Jennifer,

Well, unless the SAS syntax has changed since vs. 8.2 (which I'm still
using), the meaning of your code is clear to us but the syntax is very
wrong. That may be the cause of the warning that you get. It should be:

%GLOBAL cregion1 area;
%LOCAL i;
%LET cregion1 = AU;
%LET area = region;
%LET i = 1;

Regards - Jim.
