Execution of
DIAGNOSE code X'OO' allows a virtual
machine to examine the
VM/PC
extended-identification
code.
The register specified as Rx contains the double-word
aligned virtual storage address where the
VM/PC
extended-identification code
is
to
be
stored. The Ry register
contains the number of bytes to be stored entered as
an
unsigned binary number (maximum of
32
bytes).
The following data
is
returned
to
the virtual machine (at the
location specified by Rx):
Description
Characteristics
"VM/PC"
8 bytes,
EBCDIC
The first byte
is
the version number,
3 bytes,
the second byte
is
the level, and the
hexadecimal
third byte is the
Service Level
number.
VM/PC
CP
executes the STIDPtl
byte, hexadecimal (Store Processor
ID) instruction to determine the
version code.
VM/PC
CP
executes the STIDPt2
bytes, hexadecimal instruction to
determine the maximum length of the
MCEL
(Machine Check Extended
Logout) area.
Always zero
2 bytes,
