A Pair operations using PPRC
You can perform BC Z pair operations using TSO PPRC and ICKDSF PPRCOPY commands.
PPRC requirements, commands, and examples are provided in this topic. However, all instructions
for using the PPRC TSO and ICKDSF commands are not provided. For more information, see the
IBM user documentation.
