DIAGNOSE Code
X'lO'
-- Release
Pages
Pages of virtual storage can be released by issuing a
DIAGNOSE Code
X'lO'.
When a page
is
released, it
is
considered all zero. The register specified by Rx contains
the address of the first page to be released, and the Ry
register contains the address
of
the last page to be released.
Both addresses must be
on
page boundaries. A page
boundary
is
a storage address whose low order three digits,
expressed in hexadecimal, are zero. No completion code
is
returned, and the condition code remains unchanged.
Do
not use DIAGNOSE Code
X'lO'
to release
noncontiguous virtual storage.
