Does anyone have a really good example of using a constant function (e.g. 0: 1: ...) where it is actually necessary? Gene McDonnell uses a lot of them in At Play With J, but in the examples I've tried, 0 works just as well as 0: ...and so on.
I think the example I've used in http://www.jsoftware.com/jwiki/Vocabulary/zeroco is weak, and won't convince a novice they're of any serious use. Ian ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
