After all the "i" series machines are already using 128 bit addressing. And all their languages support it. IBM claims that the "i" has the largest number of 64-bit mode programs in existence. Someone did point out one future use for 64 bit addressing in COBOL. That would be when CICS supports COMMAREAs, and other data areas, above the bar. CICS is storage constrained even in with 31 bit addressing. However, CICS does not yet support above the bar memory areas for applications. BTW - I prefer solid examples for current need, not histrionics. -- 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
