Some of the more important fields in the volume and dataset records in the Data file are listed in the table below. Each field is assigned an internal name (a symbol in a DSECT that describes the record) and an external name (a logical name used by the user in INCLUDE and EXCLUDE statements). For a comprehensive list of these fields, see Logical Field Names for the Control-M/Tape Repository and the CTTDVL and CTTDDS members in the IOA MAC library.
