Duplicate Tape (DUPTAP)
The Duplicate Tape (DUPTAP) command copies the contents of one tape to another tape.
Notes:
- The density field in the file header labels are updated to reflect the true density.
- Byte 80 in the volume label of a tape written on device type 6157 is reset from a 'Q' to a blank.
Restrictions:
- You must have two tape drives or a tape media library device with two tape resources to use this command.
- A file that spans volumes must have both partial files duplicated at the same time. That is, duplicating a tape that ends in a partial file, followed by appending the second part of the file to the end of the tape is not allowed. You must duplicate both parts of the file at the same time by specifying multiple volumes on the FROMVOL parameter.

Element 1: Starting file sequence number
- *FIRST
- All files starting with the first file sequence are duplicated.
- 1-16777215
- Specify the starting file sequence number to be duplicated. Only the files in the specified sequence number range are duplicated.

For a tape media library device, the volume to be used is the next cartridge in the category mounted by the Set Tape Category (SETTAPCGY) command. For a virtual tape device, the volume to be used is the currently mounted one, or if there is not a currently mounted volume, the next volume in loaded status in the image catalog will be used.
