VMS Help CMS, CREATE, ELEMENT *Conan The Librarian (sorry for the slow response - running on an old VAX) |
|
Creates one or more new elements in a CMS library from an existing
file.
Format:
CREATE ELEMENT element-expression "remark"
| 1 - Restrictions |
o If you specify the /NOTES qualifier, you must also specify the
/POSITION qualifier on the same command line.
| 2 - Command Parameters |
element-expression
Specifies one or more elements to be created. If you do not
specify the /INPUT qualifier (or if you specify /INPUT without
a value), the element name must correspond to an existing file
in your current default directory. The name cannot be the same as
any existing element name in the library. Do not use the file name
00CMS because this name is reserved for library control files.
Generation 1 of the new element is created. An element expression
can also be a list of element names separated by commas, or a
wildcard expression.
remark
Specifies a character string for the creation remark of the
element to be logged in the history file with this command. The
remark is stored with both the element and its first generation.
The remark is enclosed in quotation marks. If no remark was
entered, a null remark ("") is logged.
| 3 - Description |
The CREATE ELEMENT command creates the first generation of a new
element by moving the input file into a CMS library. By default,
CMS searches for the file in your current default directory.
You can direct CMS to use a file in a different directory by
specifying the /INPUT qualifier. After the element is created, CMS
deletes all versions of the file used to create the new element.
If you specify either the /KEEP or /RESERVE qualifiers, CMS does
not delete the file.
When you create an element, you can also define the history,
concurrent, notes, position, reference copy, and review attributes
for the element or establish a reservation.
CMS stores the creation date and time, the revision date and time,
file attributes, and the file revision number of the file used to
create generation 1 of the new element. When you fetch or reserve
a generation of an element, CMS restores the times, attributes,
and file revision number associated with the file used to create
the element generation. You can also display this information by
using the SHOW GENERATION/FULL command.
To change the creation remark associated with the element or
generation 1 of the element, use the MODIFY ELEMENT or MODIFY
GENERATION command, respectively.
| 4 - Qualifiers |
4.1 - /CONCURRENT (D)
Specifies whether this element can have multiple reservations.
After you have created the element, you grant or deny concurrent
access by using the MODIFY ELEMENT command.
4.2 - /CONFIRM
Controls whether CMS prompts you for confirmation before each
transaction.
When you specify /CONFIRM and run CMS in interactive mode, CMS
prompts you for confirmation. If you type YES, ALL, TRUE, or 1,
CMS executes the transaction. If you type NO, QUIT, FALSE, 0,
or press RETURN or CTRL/Z, no action is performed. If you type
any other character, CMS continues to prompt until you type an
acceptable response.
CMS does not prompt for confirmation in batch mode.
4.3 - /HISTORY="string"
Establishes the history attribute for the element. If an element
has the history attribute, its history is included in the file
when you retrieve it with the FETCH or RESERVE command.
The quoted string specifies the format of the history. The quoted
string must contain the characters #H or #B (lowercase is allowed)
and can contain other printing characters. To include a quotation
mark in the output history string, type it twice (""). To include
a number sign (#) in the output history string, type it twice
(##).
4.4 - /INPUT[=file-specification]
Specifies the file to be used to create the element. When you
specify an alternative location for the input file, CMS deletes
the file from the alternative location (unless you specify /KEEP
or /RESERVE). If you do not specify this qualifier, CMS searches
your current default directory for a file with the same name as
specified with the element expression parameter on the command
line. Wildcards are allowed.
CMS must be able to create a unique element for each file in the
input file list. Thus, if you use wildcards in the /INPUT file
specification to specify more than one input file, you must also
use wildcards in the element-name parameter.
4.5 - /KEEP
Controls whether CMS deletes all versions of the file used to
create the new element. If you specify /KEEP, CMS does not delete
the file.
4.6 - /LOG (D)
Controls whether CMS displays success and informational messages
on the default output device. By default, if the command executes
successfully, CMS displays a success message. If you specify
/NOLOG, success and informational messages are suppressed. Any
warning, error, or fatal error messages are displayed regardless
of whether /LOG or /NOLOG is specified.
4.7 - /NOTES="string"
Establishes the notes attribute for the element. If an element has
the notes attribute, notes are appended to the lines of the file
when it is retrieved by the FETCH or RESERVE command.
The quoted string specifies the format of the note. The quoted
string can contain text or the characters #G (or #g), or both. If
you specify /NOTES, you must also specify /POSITION.
4.8 - /POSITION=n
Establishes the position attribute; that is, the character
position where the note generated by the /NOTES qualifier begins
on the line. The value n is required and must be an integer in
the range 1 to 511. The /NOTES qualifier is required with the
/POSITION qualifier.
The note is placed to the right of the text of the line. If the
length of the line is less than n, the note appears at position n.
If the length of the line is greater than or equal to n, the note
is placed at the next tab stop after the end of the line. (Tab
stops are at position 9 and every eight characters thereafter.)
4.9 - /REFERENCE_COPY
4.10 - /NOREFERENCE_COPY
Controls whether CMS maintains a reference copy of the element.
You must have established a reference copy directory.
The presence of the reference copy attribute for an element is
inherited from the library, that is, if a reference copy directory
is established for the library, by default, the attribute is
enabled for the element. You can override the reference copy
attribute by specifying /NOREFERENCE_COPY.
If a reference copy directory has been established for the CMS
library, CMS creates a reference copy of the new element and
updates the reference copy directory each time you create a new
main line generation of that element. When CMS places a file in
the reference copy directory, it also deletes any earlier versions
of that file in the reference copy directory.
4.11 - /RESERVE
Controls whether the new element is to be reserved after it is
created. When you specify /RESERVE, CMS does not delete the file
used to create the element. Generation 1 of the newly created
element is automatically reserved.
If you omit both the /RESERVE and the /KEEP qualifiers, CMS
deletes all versions of the file used to create the element.
4.12 - /REVIEW
Specifies that new generations of the element are marked for
review. By default, new generations of the element are marked
for review only if the reserved generation was either rejected
or has a review pending. If you specify CREATE ELEMENT/REVIEW,
generation 1 of the element is also marked for review.
You can change the review attribute with the MODIFY ELEMENT
command.
| 5 - Example |
CMS> CREATE ELEMENT INIT.FOR "initialization routines"
%CMS-S-CREATED, element DISKX:[PROJECT.CMSLIB]INIT.FOR created
This command creates an element named INIT.FOR from a file
with the same name in the current default directory, and
then deletes all versions of that file in the current default
directory.
