Hi, 3 i. (i. 5) index is useful. I wondered where the convention came from of having not found equal the # count of items (since all valid indexes are zero to n-1) came from? Is this because it is more efficient to use a unsigned integer in the C code that constitutes J since we are making better use of the number space?
I sometimes get a version of coders writers block due to previous ingrained conventions whereby not found would be null / NaN / -1 / 0 / false, etc. --Steven ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
