Dear J Forum: Thank you for telling me about 128!:5. However, I found something better for my needs. I need to exclude _ and __ also. So I just have J check for '__ < x < _', which ferrets out _. because indeterminant is not orderable even with the infinities. Sincerely,
Leigh ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
