I've seen very many apps people who didn't know about block size efficiencies. Many had over 15 years experience. I knew one who had just copied the same FD's for many years, just changing the LRECL, as needed, and leaving BLOCK CONTAINS 1 in. He didn't understand the need for a 'better' BLKSIZE. I ended up giving a presentation to his whole department, a long time ago (pre-SDB/LARGE Blocks), on what efficiencies could be gained. Over the span of a year, we saw improvements to the batch window, and tape/disk utilisation. They didn't make a project out of it; they just modified the FD's, whenever they had to open up the programme. - Too busy driving to stop for gas! ---------------------------------------------------------------------- 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
