INIT IXX (Format Index Area)

The INIT IXX option formats the Index Area (IXX) data set blocks. It updates the first block with control information. This first block is subsequently updated when maintenance is performed. The default block size is 4096 for all devices, except for 3380 devices which have a block size of 3860.

Note: When you specify YES for the optional keyword VERIFY=, information in the control block is preserved instead of being lost. For more information, see the description of VERIFY= in the table that begins on page How to Use for more information on VERIFY=.
