Peter, That argument (often heard) ignores the CPU savings from reduced physical I/O. Don't believe me? Run your own test. Run 2 Repros against a fairly large VSAM file. Use 1 MB of bufsp for one test, the default for the other, then compare the amount of CPU used for each run. The net of using compressed and SMB is more efficient batch using less cpu. Dave O'Brien

I am given to understand you can't limit the usage of Compressed after allowing Extended, but I have not done my own RTFM to verify or refute that. ---------------------------------------------------------------------- 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
