July 1975
1.0 SUMMARY
This release supports all monitors up to 602. It supersedes all
previous versions and answers all SPR's received before July, 1975.
Support for EXE crash files has been included. A "SYS x" command will
look first for CRASH.EXE and if this lookup fails a lookup of the file
"CRASH.XPN" will be done.
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: and load with HELPER.REL on
REL:. Place SYSTAT.SAV on SYS: together with SYSTAT.HLP on HLP.
5.0 INTERNAL CHANGES
Edit #
151 SYS OCL did no longer work due to edit 145.
152 Use new format of num tab table starting with monitor load 722.
153 Use new DDB entry DEVJOB starting with load 722.
154 Use the length of a short DDB to calculate the address of DDB
entry DEVFIL.
155 Use TRMNO.UUO to determine line numbers with non TOPS10
monitors.
SYT473.DOC Page 3
156 The command sequence:
.ASS DSK LPT
.SYS /L/X
resulted in the execution of an illegal UUO.
157 Replace all DDB offsets by a symbol DV.XXX to prevent
duplication of UUO names.
160 Never use a zero uptime to compute percentages.
161 Disk errors are reported wrong for a crash file.
162 Print system header immediately on a SYS X command, as this
saves much time if one looks at the wrong crash.
163 Subtract the size of the monitors high segment from the core
size when free core is computed.
164 Old support for reading EXE crashes.
166 Add swapping space last message.
167 Increase remote station loop restriction.
170 Typing continue gives a logged in user of SYSTAT the message
"KJOB".
171 Typing a SYS X command gives the wrong date.
172 The value of UDB offset UNIXRA was changed in 602 causing
extended writes and reads column to be wrong.
173 Ignore all packs and structures with:
1. zero mount count
2. pack not mounted
3. pack offline
4. zero reads and writes done.
174 SYS X will give an error message when a non-disk device
contains the crash file.
175 Use universal JOBDAT file and request HELPER from REL.

1.0 SUMMARY
Systat version 472 has been updated to run with 507 and 601 monitors.
In addition to this all know problems have been fixed. Note that this
version uses a help file.
NOTE: NO DATE 75 DEPENDENCY
2.0 EXTERNAL CHANGES
The V command will give "paged output". This means that the user has
to force the continuation of SYSTAT by typing random character, this
mode is intended for VT05 type terminals.
The X command accepts currently a file specification, note that this
specification has to be separated from the X by either a slash or a
blank.
3.0 KNOWN BUGS AND DEFICIENCIES
None.
4.0 INSTALLATION INSTRUCTIONS
SYSTAT currently uses a help file and requires the file HELPER.REL to
be linked in the low segment.
See file SYSTAT.CTL for explicit instructions.
5.0 INTERNAL CHANGES
1. Illegal memory reference problem.
2. SYS ..... (many dots).
No longer gives illegal memory reference or expands SYSTAT.
3. The PDB data for crash files is listed correctly.
4. SYS LEF no longer produces an empty file.
SYT472.DOC Page 8
5. Before writing the disk file SYSTAT.TXT a CHKACC UUO is
performed to verify the write privilege.
6. Spooled devices are listed with a quote sign in the operator
output.
7. The amount of swapping space lost will be reported correctly.
8. Users will be warned, that no operator is on duty.
9. SYSTAT.HLP has been updated to conform to the 507 - 601
monitor.
