When allocating new data sets, there are several methods you can use to specify the data set attributes. You can individually use the storage attribute parameters with the SITE and LOCSITE subcommands or the hlq.FTP.DATA data set. Or, if your system administrator has used the Storage Management Subsystem to group together default attributes into named classes, you can specify those class names on the DATAClass, STORclass, and MGmtclass parameters.
