Is it a fair statement to say "zSeries [is] EBCDIC"? >From the zPOP:
"Although the System/360 architecture was originally designed to support The Extended Binary-Coded-Decimal Interchange Code (EBCDIC), the Instructions and data formats of the architecture are for the most part independent of the external code which is to be processed by the machine. For most instructions, all 256 possible combinations of bit patterns for a Particular byte can be processed, independent of the character which the bit pattern is intended to represent ... a machine operating in Accordance with z/Architecture can process EBCDIC, ASCII, or any other code which can be represented in eight or fewer bits per character." It's really z/OS, its subsystems, and its typical applications that are EBCDIC, not the zSeries hardware. In other words, the fact that OS/400 is EBCDIC based is a very small advantage in zSeries emulation on iSeries hardware (relative to, e.g., Pentium hardware). OTOH, other hardware characteristics such as the native I/O architecture may provide certain relative advantages - I don't know enough to comment.

There's no doubt that IBM is some way down the road with an emulation product - there are far too many rumours coming out of the wainscotting for it not to be true. Those rumours, however, have very little substance. What has most interested me is the speed with which this beast has appeared. If we are looking at the end of a long project, then the first part of it was done under much more effective security that ever before seen. I'm sceptical. I think we're looking at the results of a relatively short-term project. This might make a great deal of sense if we postulate zArchitecture on the iSeries. Crucially, both iSeries and zSeries are EBCDIC. ---------------------------------------------------------------------- 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
