SYSDPY.DOC -- Changes from V432 to V433(550)
September 1976
1.0 SUMMARY
The F display logic has been updated to support large disk
configurations by making the display pageable.
If a display with the auto roll feature off uses only part of the
screen, then the next passes will keep adding data to the display
until all lines are used.
Unprivileged users will have TTY line numbers displayed.
This release supports all monitors up to 602 and supersedes all
previous versions.
2.0 EXTERNAL CHANGES
None.
3.0 KNOWN BUGS AND DEFICIENCIES
None.
4.0 INSTALLATION INSTRUCTIONS
Compile with C.UNV and JOBDAT.UNV on UNV:.

EDIT #
507 On DC72 (DECSYNC version) a VT05B will not work at a 2400 baud
rate as 0 fill characters disappear, this is due to the DC72
being assembled with feature switch FTT OFN .NEQ. 0.
510 Display line numbers for unprivileged users by using the TRMNO.
and DEVNAM UUO.
511 Start using the new format of "NUMTAB table" with load 721.
512 Start using the new devjob entry in DDB's.
513 Make the F display pageable.

514 Correct errors in 602 device logic.
515 Correct character input logic
516 Make C file a universal file.
517 Correct errors introduced by edit 513.
520 Wait a while between displays to give a user the time to read the
display.

526 The PEEK facility was not recognized.
527 Do not display an empty F display.
530 Adapt to changed JUMPPT macro.
531 Unprivileged jobs get data for CPU1 on a single CPU system.
532 Add the monitor high segment size to the monitor size.
533 Search universal JOBDAT file for JOBDAT bymbols.
534 Jobs locked into core cannot refresh the screen.
535 Too many "DEV BY HOW" headers are printed when a display ends at
the bottom of a column.

SYY432.DOC -- Changes from V1 to V2
June 1974
1.0 SUMMARY
This version of SYSDPY supports up to monitor 6.01 with virtual
memory. The main changes are:
1. SYSDPY uses less CPU time
2. A M display has been added
3. More help is supplied
Note: No DATE75 dependency
2.0 EXTERNAL CHANGES
2.1 M Display
The M display is activated by typing the M command. The display
consists of 2 sections:
1. General system information on the first 2 lines
2. A header line followed by job data
The general information displays on:
line 1 the system identification
the current system paging rate
(in page faults per second).
line 2 the maximum amount of available
virtual memory and the amount
currently in use.
The output format is:
VM (MAX=XXX, USED=YYY)
The maximum paging rates for both the system and user in the format:
PGR.(SYS=XXX, USER=YYY)
The accumulated page fault counts of page faults with page not in the
working set (NIW) and the page faults with the page in the working set
(IW). The format is:
PFC NIW=XXX IW=YYY
SYY432.DOC Page 6
The job data displayed is very similar to the normal display. Three
new columns are added:
1. VIRT. Under this heading is printed:
LOW + HIGH(MAX) where:
LOW=size of low segment if job is virtual else 0
HIGH=size of high segment if job is virtual else 0
MAX=maximum possible amount of virtual core.
2. PHYS. Under this heading the physical guideline is printed.
3. PGR. Paging rate in page faults per second.
2.2 Additional Help Messages
A set of additional displays have been added to inform the user of
restrictions to which he is subjected. An unprivileged user cannot
run the F display as he lacks SPY or PEEK privileges. All these help
texts are automatically replaced by the normal display.
2.3 Screen Updating
The updating of the screen is done in one pass and no longer by
updating the left half followed by the right half.
3.0 KNOWN BUGS AND DEFICIENCIES
None.
4.0 INSTALLATION INSTRUCTIONS
None.
SYY432.DOC Page 7
5.0 INTERNAL CHANGES
1. The construction of the display image has been considerably
sped up by taking out unnecessary code and replacing GETTABs
by SPY and PEEK operations is possible.
2. Swap error counts were computed in the wrong way.
