Qualifiers
/ACCESS_MODE
/ACCESS_MODE=mode
Displays names defined in the specified access mode and any inner
access modes. You can specify one of the following keywords to
indicate the access mode: USER_MODE, SUPERVISOR_MODE, EXECUTIVE_
MODE, or KERNEL_MODE.
The default value for this qualifier is USER_MODE; by default any
definitions in all four access modes are displayed.
/ALL
/ALL (default)
Indicates that all logical names in the specified logical name
tables are to be displayed. If you do not enter the /PROCESS,
/JOB, /GROUP, /SYSTEM, or /TABLE qualifier, all logical names
in the tables specified by the logical name LNM$DCL_LOGICAL are
displayed.
/CLUSTER
Displays all the logical names in all clusterwide tables (for
example, the LNM$CLUSTER and LNM$SYSCLUSTER tables).
/DESCENDANTS
/DESCENDANTS
/NODESCENDANTS (default)
Controls whether the system displays names from the specified
logical name table and any descendant tables. A descendant table
is created by the CREATE/NAME_TABLE command, with the /PARENT_
TABLE qualifier specifying its parent table. If you use the
/DESCENDANTS qualifier, you must also use the /TABLE qualifier.
/EXACT
Use with the /PAGE=SAVE and /SEARCH qualifiers to specify a
search string that must match the search string exactly and must
be enclosed with quotation marks (" ").
If you specify the /EXACT qualifier without the /SEARCH
qualifier, exact search mode is enabled when you set the search
string with the Find (E1) key.
/FULL
Displays more detailed information for the specified logical
name. The information includes the access mode, attributes, the
translation, and the logical name table.
/GROUP
Indicates that only the group logical name table is to
be searched. The /GROUP qualifier is synonymous with the
/TABLE=LNM$GROUP qualifier. If you specify the /GROUP qualifier
and you do not also specify a logical name, all names in the
group table are displayed.
/HIGHLIGHT
/HIGHLIGHT[=keyword]
Use with the /PAGE=SAVE and /SEARCH qualifiers to specify the
type of highlighting you want when a search string is found. When
a string is found, the entire line is highlighted. You can use
the following keywords: BOLD, BLINK, REVERSE, and UNDERLINE. BOLD
is the default highlighting.
/JOB
Indicates that only the job logical name table is to be searched.
The /JOB qualifier is synonymous with the /TABLE=LNM$JOB
qualifier. If you specify the /JOB qualifier and you do not also
specify a logical name, all names in the job logical name table
are displayed.
/OUTPUT
/OUTPUT[=filespec]
/NOOUTPUT
Controls where the output of the SHOW LOGICAL command is sent.
By default, the output of the SHOW LOGICAL command is sent to the
current SYS$OUTPUT device (usually your terminal). To send the
output to a file, use the /OUTPUT qualifier followed by a file
specification.
The asterisk (*) and the percent sign (%) wildcard characters
are not allowed in the file specification. If you enter a partial
file specification (for example, specifying only a directory),
SHOW is the default file name and .LIS is the default file type.
If you enter the /NOOUTPUT qualifier, output is suppressed.
/PAGE
/PAGE[=keyword]
/NOPAGE (default)
Controls the display of information on the screen.
You can use the following keywords with the /PAGE qualifier:
CLEAR_SCREEN Clears the screen before each page is displayed.
SCROLL Displays information one line at a time.
SAVE[=n] Enables screen navigation of information, where n
is the number of pages to store.
The /PAGE=SAVE qualifier allows you to navigate through screens
of information. The /PAGE=SAVE qualifier stores up to 5 screens
of up to 255 columns of information. When you use the /PAGE=SAVE
qualifier, you can use the following keys to navigate through the
information:
Key Sequence Description
Up arrow key, Ctrl/B Scroll up one line.
Down arrow key Scroll down one line.
Left arrow key Scroll left one column.
Right arrow key Scroll right one column.
Find (E1) Specify a string to find when the
information is displayed.
Insert Here (E2) Scroll right one half screen.
Remove (E3) Scroll left one half screen.
Select (E4) Toggle 80/132 column mode.
Prev Screen (E5) Get the previous page of information.
Next Screen (E6), Get the next page of information.
Return, Enter, Space
F10, Ctrl/Z Exit. (Some utilities define these
differently.)
Help (F15) Display utility help text.
Do (F16) Toggle the display to oldest/newest
page.
Ctrl/W Refresh the display.
The /PAGE qualifier is not compatible with the /OUTPUT qualifier.
/PROCESS
Indicates that only the process logical name table is to
be searched. The /PROCESS qualifier is synonymous with the
/TABLE=LNM$PROCESS qualifier. If you specify the /PROCESS
qualifier and you do not also specify a logical name, all names
in the process table are displayed.
/SEARCH
/SEARCH="string"
Use with the /PAGE=SAVE qualifier to specify a string that you
want to find in the information being displayed. Quotation marks
are required for the /SEARCH qualifier, if you include spaces in
the text string.
You can also dynamically change the search string by pressing the
Find key (E1) while the information is being displayed. Quotation
marks are not required for a dynamic search.
/STRUCTURE
/STRUCTURE
/NOSTRUCTURE (default)
Controls whether the system displays the "family tree" of all
accessible logical name tables. The display includes the two
logical name directory tables (process and system) and all
logical name tables cataloged in these directory tables. Any
descendant logical name tables are shown under their parent
tables.
If you specify the /STRUCTURE qualifier, you cannot use any other
qualifiers except /ACCESS_MODE, /FULL, and /OUTPUT.
/SYSTEM
Indicates that only the system logical name table is to
be searched. The /SYSTEM qualifier is synonymous with the
/TABLE=LNM$SYSTEM qualifier. If you specify the /SYSTEM qualifier
and you do not also specify a logical name, all names in the
system table are displayed.
/TABLE
/TABLE=(name[,...])
Specifies the tables you want to search. If you specify only one
table, you can omit the parentheses. The asterisk (*) and the
percent sign (%) wildcard characters are allowed. Names with
wildcards are used to match table names. Names without wildcard
characters are treated both as table names and table search lists
(whichever is appropriate).
You can use the /TABLE qualifier to specify the following:
o A user-defined logical name table (created with the
CREATE/NAME_TABLE command)
o The process, group, or system logical name tables
o The process or system directory tables
If you specify the table name by using a logical name that
translates to more than one table, then each table is searched
in the order specified. For example, if you specify SHOW
LOGICAL/TABLE=LNM$FILE_DEV, and LNM$FILE_DEV is equated to
LNM$PROCESS, LNM$JOB, LNM$GROUP, and LNM$SYSTEM, then the
process, job, group, and system tables are searched, in that
order.
If you do not specify the /TABLE qualifier, the default is
/TABLE=LNM$DCL_LOGICAL.
/WRAP
/WRAP
/NOWRAP (default)
Use with the /PAGE=SAVE qualifier to limit the number of columns
to the width of the screen and to wrap lines that extend beyond
the width of the screen to the next line.
The /NOWRAP qualifier extends lines beyond the width of the
screen and can be seen when you use the scrolling (left and
right) features provided by the /PAGE=SAVE qualifier.
