No. That would be a 28-bit address. A 31-bit address can go up to x'7FFFFFFF'. And the line is at 16 MB, determinied by the a 24-bit address. The hightest address below the line is x'00FFFFFF'. The first address above the line is x'08000000'. -- Tom Marchant ---------------------------------------------------------------------- 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
