Yes, the reason is to have large files without LP64. That's because large it's nicve to have large files work on 32 bit machines. You can more-or-less easily implement 64 bit arithmetic on 32 bit machines. Especially if you take into account that most of the 64 bit computations will have 0 in their upper 32 bits. Implementing 64 bit pointers on a 32 bit machine is rather a lot more involved. Casper -- Casper Dik - Sun Microsystems - via my guest account at the University of Amsterdam.
