Restore of ISAM Data Sets

ISAM data sets that have separate index, prime and overflow will be archived successfully, but Restore will restore them as one prime allocation with the index and overflow areas suballocated in the prime space.

Also, CA Disk lets ISAM allocate routines determine the amount of index space needed. This cannot be sufficient to allow future updates necessary.

To change the index size or other allocation attributes, or to allocate with separate prime and overflow areas, preallocate the ISAM data set and restore into it.
