30 1E Bitstring 1 USELON_VMDMODE Guest machine mode. This is as
set for internal use by CP. See
USELON_CALMODE for mode
'calculated' at.
31 1F Bitstring 1 USELON_CALSTAT User information
1... .... USELON_VMDSVMST 'OPTION SVMSTAT' has been
specified in the user's directory
.1.. .... USELON_VMDQDSPU This user has the QUICKDSP
designation, either by default or
as set by the SET QUICKDSP
command. When the user has work to
do, it will be added to the
dispatch list immediately without
waiting in the eligible list.
..1. .... USELON_CALDIAL This user is a dialed user
...1 .... USELON_CALSNA This user is connected through
System Network Architecture (SNA)
.... 1... USELON_VMDNOINS User is prevented from inserting
any tracks into the minidisk
cache. (set when SET MDC INS OFF
command is issued)
.... .1.. USELON_VMDNOFSL No MDC fair share limit applies.
Set at LOGON if the NOMDCFS option
is specified on the OPTIONS
statement in the user's directory.
.... ..1. *
.... ...1 *
32 20 Unsigned 4 USELON_VMDRELSH This user's RELATIVE share of
the system, as set in the user's
directory or via the SET SHARE
command. Set to zero if the user
is an ABSOLUTE share user, or if
this VMDBK has a virtual processor
dedicated to it, and the user is a
virtual MP user. Set to a negative
value if VMDBK has a virtual
processor dedicated to it, and the
user is a virtual UP user.
36 24 Unsigned 4 USELON_VMDABSSH This user's ABSOLUTE share of
the system, as set in the user's
directory or via the SET SHARE
command. Unit of value is a
hexadecimal factor scaled 16 bits.
For example,
X'00010000'=1.00(100%),
X'0000C000'=0.75(75%),
X'00008000'=0.50(50%), etc. Set to
zero if user is a RELATIVE share
user.
40 28 Bitstring 1 USELON_CALMODE Architectural mode of the
virtual machine
1... .... *
.1.. .... USELON_CALMESA ESA architecture
..1. .... USELON_CALMXA XA architecture
...1 .... USELON_CALM370 370 architecture
.... 1... USELON_CALMXC XC architecture
.... .1.. USELON_CALMESAM ESA mode user has entered z/Arch
mode. Note that at this time it is
impossible for a guest to show up
as having entered z/Arch mode at
logon time because guest has not
had an opportunity to issue SIGP
in order to enter z/Arch mode.
.... ..1. *

41 29 Bitstring 1 USELON_VMDSTYPE Storage type this virtual
machine resides in. X'00' => V=V.
X'80' => V=R. X'40' => V=F.
42 2A Bitstring 1 USELON_CALSHARF Set Share flags
1... .... USELON_VMDMXSHA Max share is Absolute if ON. Max
share is Relative if OFF.

43 2B Unsigned 1 * Reserved and available for IBM
use.
44 2C Unsigned 4 USELON_VMDSSIZE Virtual machine size, in bytes.
This field is kept for
compatability reasons, but may not
be accurate for z/Arch systems
where larger virtual machines are
valid. The preferred field is
USELON_ASCDEFSZ
48 30 Unsigned 4 USELON_VMDMXRVP Number of pages reserved for the
user
52 34 Character 8 USELON_VMDACTNO User accounting number
60 3C Character 8 USELON_VMDGRPN RACF ACI group name
68 44 Character 8 USELON_CALTODON Time at which the user logged on
for this session. In time-of-day
(TOD) clock format. To get the
user's connect time, subtract this
time value from the time stamp in
the record header's MRHDRTOD.
76 4C Character 8 USELON_VMDBYVAL The BYUSER ID that logged on
this virtual machine. If there is
no BYUSER, this field is binary
zeros.
84 54 Unsigned 4 USELON_VMDMXSHR The user's Max share of the
system, as set in the user's
directory or via the SET SHARE
command. This value is set to zero
if no Max share exists. If the Max
share is Absolute, then the unit
of the value is a hexadecimal
factor scaled 16 bits. For
example, X'00010000' = 1.00(100%),
X'0000C000' = 0.75(75%),
X'00008000' = 0.50(50%), etc.
Check USELON_VMDMXSHA to determine
if Max share is absolute or
relative.
88 58 Character 8 USELON_ASCDEFSZ Defined storage size in
addressable bytes, minus one. If
DEF STOR CONFIG was used to define
multiple discontiguous extents of
addressable defined storage, this
field contains the sum of the
sizes in bytes of all of the
individual extents (minus one).
The minus one notation is used so
that a total size of 16 Exabytes
may be represented without
ambiguity (as
x'FFFFFFFF_FFFFFFFF').
88 58 Character 4 USELON_CALDEFHI high four bytes
92 5C Character 4 USELON_CALDEFLO low four bytes
