No, the organization or company that the user works for mostly does :)

PS in more fairness it is a user problem. The user chooses the OS and
not the OS the user :)

no. (per IDL)
yes. (per current computers and OSes)
I struggled with it quite a bit, and there is nothing
like a 64 bit OS with 16gb of ram to suddenly turn
the "unable to allocate memory" problem get filed
with "what if I am on dialup and call waiting comes in".
cheers,
bob
PS in fairness, i think it is a OS problem, not an IDL
problem, in most cases.

this is not so much software related...
1) use IDL under Linux or windows 64 bits (both remove the limit of 2gb
max per process, and you have less/no "random RAM location" in use,
meaning bigger chunk of contiguous memory)
2) break your work in chunks... don't create 1 big array, but 2 small
ones etc. I often use a function that finds the available memory, and,
depending on the memory I will use in my own function, I decide what it
the max size of the array.

I think everyone now believes the answer is a 64-bit
operating system and fervent prayer that you can
somehow get your software working on it. :-)
Cheers,
David
