Add and Load functions: The dataset name of the input file containing the segment data.
Unload function: The dataset name of the output file for the segment data.
Useq function: The dataset name of the output file for the SDEP segment data.

Default:

DSN(*.DBU)

Add and Load functions: If you specify the basename of filespec as an asterisk (*) it is replaced by the DBD name. The input dataset resides in the current directory unless you specify a drive and/or directory.; The input file name, not including the drive and directory, must not be the same as the name of the files for the database. The data files for a database named MYDBD, for example, would be MYDBD.DAT and MYDBD.IDX, and the input file name cannot be either of these file names. We recommend using unique extensions for the output file names. This is enforced even if the database data files are in a different directory than the input file.
