I suspect it depends on the details. Here is an example of a program that fails due to lack of memory on 32 bit systems but will run to completion on 64 bit systems. It will run in a reasonable length of time with 8 gigabytes of memory. With less than 4 gigabytes of memory, it takes much longer. http://www.jsoftware.com/jwiki/JDB/Netflix -- David Mitchell ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
