The actual supporting FBA devices?

That the restriction applies to LPA list, SYS1.NUCLEUS and
SYS1.PARMLIB testifies to management short-sightednes.  Putting code
into IPLTEXT and SYS1.NUCLEUS to read PDSEs should not have been that
difficult.  If IBM had carried forth the vision in original VSAM which
included sequential data sets, FBA devices could have been used only
for FBA formatted data (VSAM, PDSE, Unix files, etc.) with CKD files
being migrated at the installation priority.  Instead, countless
machine cycles and DASD bytes are wasted fitting FBA files poorly to
CKD architecture with in turn fits poorly on to the actual supporting
CKD devices.
