(The RBA of the next completely unused control interval.)SPACE-PRI—Gives the number of units (indicated under TYPE) of space allocatedto the data or index component when the cluster was defined. This amount ofspace is to be allocated whenever a data component, a key range within the datacomponent, or the data component’s associated sequence set (if IMBED is anattribute of the cluster) is extended onto a candidate volume.SPACE-SEC—Gives the number of units (indicated under TYPE) of space to beallocated whenever a data set (or key range within it) is extended on the samevolume.SPACE-TYPE—Indicates the unit of space allocation:CYLINDER—CylindersKILOBYTE—KilobytesMEGABYTE—MegabytesTRACK—TracksAppendix B.
