I'm doubt &prefix:<->:(Whatever) is defined at all, so that's probably a run-time failure unless someone defines the appropriate multi. And if the - fails it never even gets to the x or xx. The * token doesn't mean infinity. It means that the operator you feed it to has to figure out what it means. Some operators interpret * to mean infinity. But infix:<-> interprets a * on the left to mean the end of the current subscript range. And the range operator interprets * to mean either negative or positive infinity depending on whether it's on the left or the right. We don't require (or even allow) people to say -*..* as it currently stands. Larry
