Load library members have imbedded channel programs. Moving a load
library to an FBA disk might have been a challenge.

All partitioned datasets have keyed directory blocks.

VTOCs are keyed datasets (or were, I don't how the newer format
introduced with the DF products worked).

However, VSE has the same VTOC format.
