Dear Angelica:
2.2 GB is essentially the largest integer you express with 32 bits
(2^31), and therefore the largest quantity of memory for which you can
define an address. There are some tricks that really sophisticated
programmers can do that let you use more than that, but I don't know how
to do it. If you want to access more memory, you have to go to a 64-bit
machine and operating system.

Dear group:
I am developing a program using Python 2.5.4 in windows 32 OS. The amount of
data it works with is huge. I have managed to keep memory footprint low, but
have found that, independent of the physical RAM of the machine, python always
gives the MemoryError message when it has occupied exactly only 2.2 GB. I have
tested this in 4 different machines, all with memory of 3 to 4 GB... I'm amazed.
Could any of you please help me to figure out how to change that limit? I typed
help(MemoryError) and it is a class itself, but that help told me nothing I can
use...
Thanks,
Angelica.
