I was sitting here in front of an Excel spreadsheet, thinking, "you know this is an array" ... not too long ago I was looking at a database table and thinking the same thing.
HOWEVER. isn't a tree the most general data structure? You can make lists out of trees and make arrays out of lists. Therefore the most fundamental and broadly applicable data structure is a tree and not an array. Any feedback on why J is an array processing language and how it might handle tree/hierarchical data is appreciated. And how good is J with infinite data structures/streams? ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
