YMMV on that...
"When you obtain storage, the system clears the requested storage to
zeros if you obtain either:
8192 bytes or more from a pageable, private storage subpool.
4096 bytes or more from a pageable, private storage subpool,
with BNDRY=PAGE specified.
In all other cases, you must not assume that the storage is cleared
to zeros.
The caller can specify CHECKZERO=YES to detect these and other
cases where the system clears the requested storage to zeros."
