[Jprogramming] J's limit on space

[David Vaughan]

On a related note, I think there's a bug in the Mac version of j701. It doesn't seem to recognise when it has run out of memory and brings my system to a crawl.

This has happened with operations involving data thats starts off as something like i.1e10, which on its own is considerably less than 2^62.
