Note: there is no "64-bit Mac". There are 64-bit applications that run on the same Mac. It may be easier on Intel Leopard, though Tiger should support it too. It may require Xcode 3+. http://developer.apple.com/macosx/64bit.html http://www.apple.com/macosx/technology/64bit.html There is one big caveat with 64-bit apps. Typically you don't need 64-bit ints or even individual arrays with >4 bil iteams, because in J large ints are automatically coerced to doubles. It is the address space limitation that is overcome, as in JDB. However, undesirably with 64-bit you also double the storage for ints, which puts the burden on your physical RAM, and disk swapping descends. Is that a viable rationale? ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
