Tom: As John Ells indicated it is no longer an option and all datasets are created with a EOF. As he indicated IIRC it was in Z/os 11. I must admit that it slipped by me when it became a default and is no longer needed in IGDSM00

What keyword is that, Ed? I don't remember that and a quick scan of the keywords for IGDSMSxx doesn't reveal anything. I do see this in DFSMS Implementing System-Managed Storage section 8.1 Understanding the Benefits of Placing Batch Data under System Management: <quote> For sequential data sets, SMS writes a hardware EOF at the beginning of the data set at initial allocation. This prevents data integrity problems when applications try to read the data before data is written in the data set. </quote> There is nothing there about needing to do anything special to enable the function. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
