Can anybody explain what the new array format provides that the old

If you read the above revup article, then all the new features are
described there. If that's too cumbersome, here a short list:
multi dimensional:
Arrays used to be of the form "theArray[theKey]" workarounds had to be
employed to store hierarchical data in an array: "put "rex" into
theArray["animals, dogs, jorkshire, name"]". Many additional steps had
to be done to access such data, and certain things would have been way
too complex. With the new arrays there can be "true" hierarchical data
stored, especialy for nonsequential access, this simplifies a lot of
things: "put "rex" into theArray["animals"]["dogs"]["jorskshire"]
["name"].
first level data structure:
Arrays could not be passed as values to functions or handlers, nor
returned as result from them. This again simplifies things like the
recursive directory walker I made as an example yesterday in this
thread.
have fun
