| SYSTEM
| logical name:
---
prints the logical names and definitions
which have been established for your
job, for the system, or for both; or
prints the job-wide and system-wide
definitions of the specified logical
name. Establish and withdraw logical
names with DEFINE.
For the DEFINE and INFORMATION
LOGICAL-NAMES commands, a colon
following the logical name is optional.
However, in INFORMATION LOGICAL-NAMES
the logical name SYS: must always be
followed by a colon. Otherwise, the
system interprets SYS as an abbreviation
for the SYSTEM argument.
The wildcard characters, * and % can be
included in the logical name. For
example, type A* to list all logical
names that begin with the letter 'A'.
See example 6.
Default - JOB
---
MAIL | user name tells whether there is unread mail for
| SYSTEM the user, if you have read access to
--- the user's mailbox; otherwise, you see
only the message, "Mailbox protected."
Also, displays any system messages since
your last login when you type SYSTEM
instead of user-name. Send mail with
one of the two mail programs, MAIL and
DECmail/MS. Read mail with the RDMAIL
or DECmail/MS program.
Default user name - your user name
MEMORY-USAGE prints, for the current process of your
job, the following:
o the number of pages of memory
assigned

program's entry vector (see with SET
ENTRY-VECTOR)
and on each succeeding line
o the page numbers of pages occupied by
a file or program
o the file specification if the pages
are file pages; the process
specification if the pages are mapped
from another process; PRIVATE
otherwise.
o the page numbers of file pages or
process pages. If a page is mapped
by indirect pointers, the file
specification is printed to which it
is mapped; "Fork n" means that these
pages are mapped indirectly through
another process (process n) of the
job; "No page" can mean either of
these conditions, when the
destination page does not yet exist.
o the permitted accesses to the pages
(set with SET PAGE-ACCESS):
R - Read access
W - Write access
CW - Copy-on-Write access
E - Execute access
See Example 4 at the end of this command
description for obtaining information on
pages assigned to extended sections of
memory.

o the length of time (in hours,
minutes, and seconds) since the
monitor was reloaded
o an analysis of monitor overhead
time, by percentages
o the number of swap-reads and
-writes, and file-reads and -writes
o the number of pages of memory
available to user programs
o the number of terminal wake-ups
(occasions when a program "wakes up"
after waiting for terminal input or
output to finish, and of terminal
interrupts (occasions when a program
is interrupted by a CTRL/C, CTRL/O,
or CTRL/T (or other, user-enabled
control characters) typed at a
user's terminal)
o the average number of processes in
the balance set (NBAL, a subset of
the run set - these are runnable,
and each receives a share of total
CPU time) and in the remainder of
the run set (NRUN - these are
waiting to be run)
o the number of seconds of CPU time
given to each of the scheduler
queues (where the leftmost listing
describes the highest priority
queue, for interactive processes,
and the rightmost listing is for
CPU-bound processes)
o if class scheduling is enabled, the
allotted share and actual use of the
system (expressed as a percentage of
total CPU time) by each class, and
the 1-, 5-, and 15-minute load
averages of each class
All averages and totals are computed for
the time since system start-up.

STRUCTURE dev: gives, for each structure named, the
following:
o information as to whether the system
performs checking operations while
writing to the data or swapping
areas of the structure. The system
would perform this checking by
immediately reading the data that it
has just written. If the system
manager has enabled these functions,
the following lines appear at the
top of the display: "Write
verification for data", and "Write
verification for swapping".
o the number of users who have mounted
the structure, the number of open
files on the structure, and the

off-line files are [automatically]
retrieved) are enabled
o the system's expiration default date
for off-line files
o the current setting of the scheduler
bias control
o whether class scheduling is enabled,
and, if it is enabled, the special
class (if any) for batch jobs, and
the default class (if any)
o off-line structures timeout interval
o status of cluster information

Set with SET TAPE.
TERMINAL-MODE number gives the following information about
the specified terminal:
o its type (for example, LA36, VT52,
or SYSTEM-DEFAULT)
o its speed (baud rate), in bits per
second. If the terminal is
connected to the system through
another node, such as a
DECserver-100 or another TOPS-20
system, the terminal speed cannot be
determined by this command. This is
indicated in the display by the
message !Terminal speed
indeterminate!.

effect, and if CTRL/S and CTRL/Q
were not the specified characters)
o the length (in number of lines) and
width (in number of characters) of
its page
o whether it is capable of printing
lowercase characters, whether it is
set to raise lowercase letters you
type to uppercase, and whether it
will mark (flag) capital letters
with a single quotation mark (')
o whether it has a formfeed mechanism,
and whether it is set to only
indicate formfeeds or to perform
them
o whether it has mechanical tab stops,
whether it is set to immediately
echo input you type
o whether it is operating in
FULLDUPLEX or HALFDUPLEX mode
Set with TERMINAL. The SYSTAT command
displays terminal numbers.
VERSION tells you:
o the name of the host system
o the TOPS-20 operating system's name
and octal version number
o the octal version of the TOPS-20
command processor (EXEC) in use
o the name (and decimal or octal
version number, if any) of the
program in the current fork for
which program data vectors (PDVs)
exist and that are associated with
the current process. (See the
TOPS-20 Monitor Calls Reference
Manual and to the description of the
/PVBLOCK switch in the TOPS-20 LINK
Reference Manual for information on
PDVs.) See Example 5.
o the decimal version of the UUO
simulation package in use (if a
TOPS-10 program is in memory)
The format of a version number is:
a.b(c)-d
where: (1) a and b are respectively
incremented for major and minor changes
in the software (2) c gives a rough
indication of the number of times the
software component has been edited (3)
d, a holdover from earlier versions of
TOPS-20 which is now rarely used,
identifies the programmer(s) responsible
for the software component.
VOLUMES setname: gives the volids of currently mounted
and newly created volumes in the
specified tape set. A colon after the
tape set name is optional.
Hints
Specifying the Current Fork of TOPS-20
Use the FORK command to specify the fork to be described by
the ADDRESS-BREAK, FILE-STATUS, MEMORY-USAGE and VERSION
arguments. Find out your current fork with INFORMATION
FORK-STATUS.
Restrictions
Using the INFORMATION OUTPUT-REQUESTS /DESTINATION-NODE switch
For non-privileged users, the local node's GALAXY must know
if the remote node has printers. If the user is privileged,
then the print request queue of the node specified is
displayed, regardless of whether the local GALAXY knows if
the node has printers or not. The user specified node must
be a node in the cluster known to the local GALAXY.
If the node specified by the /DESTINATION-NODE switch is the
local node, then the print request queue of the local node
is displayed.
You cannot use an * as an argument in the /DESTINATION-NODE
switch.
