SAS might appear to hang in an endless loop if you use Cross Environment Data Access (CEDA) and select a large number of variables. This problem is most likely to occur when accessing a foreign data set using CEDA to process more than a million variables. This might slow performance to the point where SAS appears to have gone into an endless loop.
