Sequential Concatenation

z/OS DFSMS Using Data Sets
SC23-6855-00

To process sequentially concatenated data sets, use a DCB that has DSORG=PS. Each DD statement can include the following types of data sets:
  • Sequential data sets, which can be on disk, tape, instream (SYSIN), TSO terminal, card reader, and subsystem
  • UNIX files
  • PDS members
  • PDSE members

For the rules for concatenating like and unlike data sets, see Concatenating Data Sets Sequentially.

You can use sequential concatenation (DSORG=PS in DCB) to sequentially read directories of PDSs and PDSEs. See Reading a PDS Directory Sequentially and Reading a PDSE Directory.

Restriction: You cannot use this technique to read a z/OS UNIX directory.
