What __user written__ application would use more than this? I understand 64 bit addressing for system type functions. I guess. But even that is overkill because you cannot configure any z/OS system such that you could actually acquire that much addressable storage. Now, using 64 bit address space to "memory map" VSAM LDSes starts to make sense to me. "64 bit" is, for now, more marketing hype as far as I can see. But I've been wrong before, if somebody has a good, actual (not theoretical) use for 64 bit addressing in an application program. -- John ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
