>Huh? We're discussing how to get around that restriction. The point is that there is nothing to "get around". Executable code isn't supported about 2GB for numerous reasons already mentioned. Therefore the middle 64-bits of the z/architecture PSW only contain zeros. Compressing the PSW doesn't incur the loss of any data. Data loss would occur only if a 64-bit instruction address had to be preserved, but since that isn't valid, there is nothing lost.
If you attempted it, then you would experience instruction address truncation of the high order bits. Once again, there's nothing to "get around", since it simply isn't allowed. ---------------------------------------------------------------------- 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
