largest array, most memory accessible [message #41303]

I was following some of the other threads about memory size,
and wanted to see what the options are for a new computer I am considering.
(I am looking at getting a dell dimension or something in that price range and wondering
how much ram is useful. The main thing to spend money on is ram, even if I get a slower
processor)

My dream would be to have an array of complex variables of size [1024, 1024, 1024,512],
(four terrabytes of ram?) but I guess I can scrape by with arrays of [128,128,128,64] perhaps.
I cannot test out these values on my current computers.

1) What is the largest array in IDL 6.1 on a winXP machine?
Is this 2 Gb?

2) What is the largest amount of ram IDL can access, i.e. can I
make multiple copies of the array in question 1?
Is this limit also 2Gb or can IDL grab the full 4gbs?

Cheers,
bob
