Most of the catalog information displayed for the index component of the cluster is in the same format as the data fields, with the following additions:
This field represents the relative byte address of the first control interval in the sequence set of the index.
This is the number of index levels that occur in the index. For direct access retrieval of records in the data component, this number represents the number of index control intervals that must be accessed to locate the proper control interval in the data component that contains the record.
This is the relative byte address of the control interval that contains the highest level segment in the index. For direct access retrieval of records, this is the first index segment that is retrieved to begin the search for the specified key value.
This is the length of the key in the data portion of the cluster, as specified by the user when the cluster is defined.
This is the relative key position. It represents the offset from the beginning of the data record to where the key of the record can be found. An RKP of zero indicates the key starts in the first character of the data record.
