Dean, As Alan points out, it depends on blocking factor. A VSAM dataset with 4K Cis will give to 180 Cis per cylinder. So your cylinder capacity for that block size will be 737280 bytes.
As opposed to the total available capacity of 56664 * 15 = 849960 Which value are you looking for total available or useable? -----Original Message----- From: Alan C. Field Subject: Re: MB to Cyl Conversion Accurate or approximate? It depends on blocking factor, media type For 3390s I use 56664 (bytes per track) * 15 (tracks per cylinder) for an approximate value. ---------------------------------------------------------------------- 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
