With a 3120 BLKSIZE, you can get 15 records per track, or 46800 bytes per track. With a 124 BLKSIZE, you can get 75 records per track, or 9400 bytes per track. The capacity of a 3390 track is 56664 bytes. I'm not sure what number is used to calculate the space used in GB, but it is going to be the same for either data set. If you look at the space utilization for both data sets in tracks (or cylinders), and compare them in light of how much can be stored on a track, it will make more sense. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
