When you create a database file, database attributes are stored with the file and members. You specify attributes with database command parameters. For discussions on specifying these attributes and their possible values, see the CRTPF, CRTLF, CRTSRCPF, ADDPFM, ADDLFM, CHGPF, CHGLF, CHGPFM, CHGSRCPF, and CHGLFM commands in the CL Reference .
