Extended Addressability refers to an attribute of a data set that allows the data set to contain more then 4GB of data. Extended Format refers to each DASD block's having some extra bytes, called a suffix, added to the end of each data block, and this can happen with data sets that contain fewer than 4GB of data. EAV stands for Extended Addressability Volumes and refers to an attribute of a volume that allows it to have more than 65,536 (approximately) cylinders on it, regardless of what kinds of data sets are stored there or how large they are. These three buzzphrases all have the word "extended" in them, and two of them also have the word "addressability" in them, but they are three different concepts. Bill Fairchild
