IBM made a change some time ago, such that if a new extent is contiguous
with the last existing extent of a cluster, it just made the new extent
part of the existing extent.
For free space, this was in MVS/ESA 3.1.0.e.
For VSAM, this is available with either 1.7 or 1.8.
I cannot remember which.
Neither. I believe the VSAM extent consolidation enhancement was part of
the z/OS V1.5 deliverable.
