I have created a large local (called stubs) of variable stubs with wild cards e.g. "var1_* var2_* var3_*". The list is quite long (~1,000 variables) when expanded out. When I execute either keep stubs or browse stubs, I'm getting an error message "too many variables specified", which I've never seen before. As the dataset is currently loaded into Stata, I'm not sure why keeping or browsing a smaller subset would cause an issue. Any ideas?
