LISTCAT OutputEntries are identified as shown in the list that follows.v AIX—Identifies an alternate index entry.v ALIAS—Identifies an alias entry.v CLUSTER—Identifies a cluster entry.v DATA—Identifies a data entry.v GDG—Identifies a generation data group (GDG) base entry.v INDEX—Identifies an index entry.v NONVSAM—Identifies a non-VSAM data set entry.v PGSPC—Identifies a page space entry.v PATH—Identifies a path entry.v UCAT—Identifies a user catalog entry.ATT: Attributes GroupThe fields in this group describe the miscellaneous attributes of the entry. See theDEFINE command for further discussion of most of these attributes.ACT-DIC-TOKEN—The active dictionary token or NULL. This attribute is onlyvalid for compressed data sets.Note: The following information is not an intended programming interface. It isprovided for diagnostic purposes only.The first byte of the dictionary token indicates the type of compression used forthe data set.X'100. ....' indicates compression has been rejected for the data set. No data iscompressed.X'010. ....' indicates generic DBB compression is used.X'011. ....' indicates tailored compression is used.AVGLRECL—The average length of data records, in bytes. AVGLRECL equalsMAXLRECL when the records are fixed length. Do not, however, set AVGLRECLequal to MAXLRECL for variable-length relative records.Note: For variable-length RRDSs, the AVLGLRECL shown in the LISTCAT outputis 4 greater than the user-specified length, reflecting the system-increasedrecord size.AXRKP—Indicates, for an alternate index, the offset, from the beginning of thebase cluster’s data record, at which the alternate-key field begins.BUFND—The number of buffers provided for catalog data records. The default forBUFND is taken at catalog open and is not reflected in the output from LISTCAT.BUFNI—The number of buffers provided for catalog index records. The default forBUFNI is taken at catalog open and is not reflected in the output from LISTCAT.BUFSPACE—The minimum buffer space, in bytes, in virtual storage to beprovided by a processing program.CCSID—The Coded Character Set Identifier attribute that identifies a specific setof encoding scheme identifier, character set identifiers, code page identifiers, or theadditional coding required to uniquely identify the coded graphic used.CI/CA—The number of control intervals per control area.Appendix B.
