Nothing, except all the z/OS changes that you haven't considered, and all the application changes they might imply for existing applications that really don't care about 32-bit capability. One problem was mentioned earlier in this thread: ELSQA, EPVT, ECSA, ELPA, and ENUC will prevent you getting the 3GiB that you want, because they're sitting in the way today. So, in addition to the "simple" changes you want, z/OS would also have to change its storage layout. I can't predict what parts of the system that would affect and how complex it would be, or what applications it might affect. I'm sure there are more. -- Walt ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
