the reason I used 42=$0 is twofold: 1) It highlights that the argument of weather to use $0 or 0$0 was a no man's land debate.
According to weather.com, I'm going to have some rain, today. According to google's weather widget, I should experience thunderstorms. That said, perhaps it would be more useful if I focussed on the J issues. The sentence 42=$0 compares the element 42 to each of the elements in an empty array. The result should be an empty list. If you wanted to compare the array 42 to the empty array, to see if the arrays were equal (rather than an element-by-element comparison), you should have used 42-:$0 If you wanted something else, I must admit that I can't even guess at that.
2) It refers to the movie "hitchhiker's guide to the galaxy" where as everyone knows, the meaning of life is 42.
And, as everyone knows, what's really important is not the answer but the question.
I was thinking that Roger could explain the evolution from "jot" to the actual a: and make comments if required. But I suppose I was ignored and misinterpreted (as is usually the case). My only excuse is to be from a different cultural background...
It helps if you ask the question you want answered. (I did not see this question in your earlier post.) -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
