Problem confirmed on latest Win snapshot. Don't apologize for cross-checking with other software!

This should work I guess. Interestingly, if you replace Water with zeromiss(Water), then it works. Typically the result will not be what you intended, though. (Or are the zeroes actually missing values?) -sven _______________________________________________ Gretl-users mailing list Gretl-users(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-users
