Yeah, sorry, just being lazy on input, and then forgetting to clean up for general consumption. Note that the prefix form does more than save one character. It often saves you from spacing over whole expressions to where to insert the matching ]. The downside is you need to know operator precedences, or wind up needing extra parens. --rwg Meanwhile, is %152 right? And how many E^E^ do we need to reverse that sign?

There was a brief shining moment when developmental Macsyma could actually do these, using Bill Dubuque's nhayat asymptotic expansion system, inspired by a certain moderator. --rwg _______________________________________________ math-fun mailing list math-fun@mailman.xmission.com https://mailman.xmission.com/cgi-bin/mailman/listinfo/math-fun
