It's not pretty, but it would work....
IDL, like all other programming languages, actually stores the data
(even if a multi-dimensional array) in a 1-d array. To my knowledge
the only upper limit on the length of a 1-d array is due to the bit-i-
ness of your computer. A 32-bit system has a limitation of around 2
Gb (I think) and a 64-bit is much higher --- I don't think I've even
come close to the limit. Of course, once you've got all the data into
this 1-d array, you'll need some scheme of encoding which element goes
where.
