Uh, oh. It seems that I have to revert or modify the change. Anyway, it looks strange to me that right; line from 1,1 then up 1 (which is, according to your tests with AT&T pic, the same as `line 0 from 1,1 then up 1') should be have in a different way compared to right; line then up 1; (which is the same as `line right then up 1'). Am I doing something wrong? Opinions? Werner
