The short answer is that you should run J64 on either a 64 bit Windows
or Linux. These machines cost little or no more than a 32 bit system
though you may be tempted to add on lots of extra real memory.
There are some answers to your questions in the lab 'Mapped Files'.
You may also want to take a look at sparse arrays.
(nice to see you pop up here!)

Subject: [Jprogramming] limit errors
Is the limit error that I get when I try, for example
too_big =. 1e5 1e5 $ 2
telling me something about
a) the memory on my particular machine
b) a limit due to using Windows on a 32-bit architecture
c) a limit I could change if I knew how
c) an actual limit in J ?
And, relatedly, what is the recommended hardware/software environment
for
running J programs that want to process very large arrays?
(I am writing my very first application in J. Now that I have it
working on
toy problems on my laptop, I want to try it out on more realistic
ones.)
Thanks for any advice. -Michael
