I think what Jacque wanted was a more direct way to get the elements at any level of a multi-dimensional array. She certainly knows that, given:
on mouseUp put "X" into myArray[a][b][c] put "Y" into myArray[a][b][d] put myArray[a][b] into newArray end mouseUp newArray gives: c X d Y and that one can loop through whatever level of the array is of interest (the third in this case) to finally find: X Y A function can be written, as Jacque mentioned, to find this sort of thing with the desired level described as a parameter. I just thought that it would be useful to have that very thing: put elementsOrArray(theArray,theElement) into newArray as a native function.

And after changing these contents (you can even replace them by other arrays) you can do the reverse put newArray into myArray["c"]["y"] oh, I didn't see that you got answers already - Colin's says the same thing more concisely - well I send this one nevertheless. To answer your question rather than to read your answer is such an exceptional situation I'll not miss it ;-) Jacques Le 16 juin 2013 à 21:26, J.
