Well, then, no, you are probably not going to be able to
make an array that is at minimum (assuming a byte array)
1.3 GB in size. Here are some reasons why:

Tiling is a technique ITTVIS, in its wisdom, reserves only
for ENVI. (Which I think is only another $8000 or so.)
But, as far as I can tell, tiling is just writing a file
to disk, and then using the Associate Variable method of
accessing some smaller ****tion of the data, processing that,
and then storing it back to disk. (You could open the file
with OPENU, for example, or you could just have two files,
both opened as associated variables, one to read from and
the other to write to.)

No, I don't think so. I think you have to check the
newsgroup every five minutes like the rest of us. :-)
