The need for PDSE datasets and Program Objects are built into the very
core of COBOL V5.  Just a few examples of features that COBOL V5 uses
and will use that require Program Objects(PO) and thus PDSE datasets
for executables are:

Improved init/term scheme relies on user-defined classes in object, requiring PO
QY-con requires PO
(A performance improvement for RXY (long displacement) instructions.
Condition-sequential RLD support requires PO
A performance improvement for bootstrap invocation
PO can get page mapped 4K at a time for better performance
NOLOAD class DWARF debugging data requires PO
Common reentrancy model with C/C++ requires PO
XPLINK requires PO and will be used for AMODE 64
