I went out years ago and decided I should never have to worry about directory sizes. Because I experimented with 1-track datasets, I missed the EOF and thought that 44 blocks was the number per track. I never looked it up, and forgot about it over 20 years ago. I've now updated my crib-sheets, and, for those who will listen, I recommend 674 blocks as a starting point (1 cylinder), and if you really think you are going to have more than that times 4 (6, or 21), consider 645*NN-1. Where NN is the number of cylinders you want to allocate to the directory. DASD is cheap; spending mind-sweat (and time re-building them) is not! - 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
