Personally, I don't think x and y are good global names for nouns, but they can be good global names for verbs. For example: x can make a good multiplication operation (perhaps x as dot product and X as cross product). y can make a good linking operation (looks somewhat like a comma, and is the Spanish word for "and"). Also: u can make a good union operation v can work as bitwise or etc. I don't think I've ever used all of these at one time in this fashion, and I don't think these uses are particularly urgent, but I'm not sure I agree that using these names globally is always bad practice. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
