Tape to Sequential Data (option 4.2.5)
Tape to Sequential Data copies all or selected tape records to a sequential data set on disk, tape, or SYSOUT. You can specify the number of records to skip from the beginning of the file and the number of records to copy (see Specifying the number of tape files to process).
You can also use Tape to Sequential Data to convert a multiple-file tape into a single sequential data set (tape image file) which can be distributed across a network. Specify a number of files other than one, but no tape file ID or start position. See Copying tape data across a network.
Use Sequential Data to Tape (option 4.2.7) to restore the file to tape.
