Because some people actually care about speed of execution and CPU time. z9 cycles don't come cheap. Those of us trying to blead every mip out our boxes in order to save our beloved mainframe (and our jobs) have to care about these kinds of things. PDSFAST wouldn't exist if IEBCOPY was quick and efficient. COPYMOD is especially slow. Example for just 1 library: COPY of SYS1.LINKLIB to new library (same blksize): CPU 0MIN 01.00SEC SRB 0MIN 00.93SEC (35 sec wall clock) COPYMOD of SYS1.LINKLIB to new library (same blksize): CPU 0MIN 03.36SEC SRB 0MIN 00.94SEC (2 min 28 sec wall clock) Regards, Mark -- Mark Zelden Sr. Software and Systems Architect - z/OS Team Lead Zurich North America / Farmers Insurance Group: G-ITO mailto:[EMAIL PROTECTED] z/OS and OS390 expert at http://searchDataCenter.com/ateExperts/ Systems Programming expert at http://expertanswercenter.techtarget.com/ Mark's MVS Utilities: http://home.flash.net/~mzelden/mvsutil.html ---------------------------------------------------------------------- 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
