06-14-94 Miscellaneous performance enhancements.
07-07-94 Correct CP Supervisor reporting on VMSYSTEM for multiprocessor
09-02-94 Expand VMUSERS IOCOUNT filed from 8 to 9 digits.
09-19-94 Correct RDEVBLOK radix tree location calculation for VM
systems with greater than 100 megabytes of storage.
08-15-95 VMUSERS display: Field PGSEC shows the number of page faults
per second for the last interval (from VMDCTPFD).
Field XSTR shows the number of XSTORE bloks used for host
paging for the guest (from VMDCTXBK).
Field SPOL shows the number of pages spooled for this user
(from VMDPDSPL).
09-10-95 Correct RDEVSTAT Field in RDEVice display.
Show RESERVE or RELEASE of Pending, Held or spaces for device
in RDEVice display.
08-07-96 Correct computation of RAI in VMUSERS display.
RAI to interval = 1 - (number of times found in-queue/
number of times found active)
08-13-96 Correct CORESIZE field in 4-color display of VMSYSTEM.
Add Minidisk Caching statistics in VMSTORAG (PF11) display.
Place title on number of COREPAGES (CORPGS) in VMSYSEM.
Correct local non-SNA PROG470 problem on VMBLOK display.
09-09-96 Begin development of Virtual Device Microscope (VDEV).
This feature can be selected with the VDEV command from
the command line of the VMBLOK (PF4) display. The user
can then select any device defined in the virtual environment
of that user. Return will be through the VMBLOK display.
09-16-96 Expand MEM Size on VMSYSTEM display to 8 digits.
10-21-96 Make selection of next monitored real device independant of
VM Locate command response format of a given VM release.
Selection will cause search of lookaside RDEV Radix TRee
for validity and address of RDEV Block.
10-28-96 Change VMUSERS logic that looks for V=R Guest location at
SYSVRLOC to SYSVMVR, this location is interrogated only
when V=R is logged on.
Alter terminal read logic in all functions so as to disregard
the reception of nulls and spaces at command line. This was
causing problems with customers using host logical device
facility after switching screens back to VMRSM session.
11-01-96 On the VMSYSTEM display, we look at both the real storage that
is sensed at IPL time by CP and the amount of real storage
selected at generation time, if any. The figure displayed and
used in other storage calculations will be the lower of the two.
11-20-96 Re-linked with new I/O Interrupt Handler.
I/O Interrupt Trap routine was not correctly disabling I/O
interrupts on exit from Set/Reset calls.
Re-linked with new I/O module. If SSCH posts a status pending
condition we will interrogate the IRB with a TSCH instead of
exiting as we were for cc=0.
01-21-97 Show CP Nucleus Residence Size (Nuc) on VMSYSTEM display
Show number of Non_Pageable pages on STORAGE display.
Remove SPOL page count from VMUSERS display, replace with
VM Guest machine size in megabytes.
Change cummulative I/O count of VMUSERS display to I/Os
performed over last sampled interval.
Correct counter of LOCKED pages on VMDBK display, add VMSIZE.
01-27-97 Correct calculation of storage utilization. Division process
was ignoring high-order bits of dividend resulting in erroneus
results on systems with storage in excess of 1G bytes.
06-15-98 Reassemble using VM/ESA v2.2 maclibs.
09-01-98 Correct bar graph for 'PENDING' statistic of RDEV display.
10-29-98 Increase scan for active users from 100 to 400 users.
Increase scan for active devices from 256 to 1024 devices.
Correct problem of 'Command not recog...' that has been
occurring when hitting ENTER key with no command operands.
Update CPC Logo.
Make common TASKWAIT interrupt window handler.
01-18-00 Support for VM/ESA v2.4
Miscellaneous enhancements and corrections.

09-15-00 Introduce unified "interrupt wait" mechanism. Enhance interrupt handling.
Increase performance of display panel startup.
09-16-00 Capability to enter CP Commands and capture response under control of
a "rolling" console with scrolling features. Implemented as scope transition
command named "CP". Allows user to make adjustments via CP without
leaving and re-entering monitor environment.
Update the VMRSM EXEC to allow capture of IUCV messaging needed to support
the CP command.
09-20-00 Include SPECIAL class in VMDEVICE display. The class SPECIAL would include
CTCAs, 3088s and 37xx devices among others. Prior classes were DASD,
TAPE, GRAF and UR.
09-28-00 Improve handling of x'8E' situations coming from Diag x'58' screen I/O.
Improve screen I/O error routines.
09-29-00 Subprogam "convert to zoned display" procedures that are common to all
product programs.
Update RDEV display real device states.
10-22-00 Correct possible loop condition in VDEV and RDEV displays.
12-12-00 Correct screen overrun (PROG754) on VMDBK display.
12-17-00 Add logic to recover CP "rolling" message console facility following the
use of the ClearKey.
12-19-00 Update screen handling for the CP "rolling" message console facility
01-20-01 Correct Fixed-Point Divide Exception possible occurrence when
determining interval seconds, should virtual clocking not be
updated syncronously with realtime and time differentiation
results in negative or zero.
