1 – CLASS
Creates one or more empty classes. Format: CREATE CLASS class-name[,...] "remark"
1.1 – Command Parameters
class-name Specifies a name for the class. CMS reports an error if you specify a name that is already used for an existing class or group. (Class and group names must be unique.) If a previously used class or group name has been removed with the DELETE CLASS or DELETE GROUP command, you can reuse that name with CREATE CLASS. A class name can also be a list of class names separated by commas. Wildcards are not allowed. remark Specifies a character string for the creation remark of the class to be logged in the history file with this command. The remark is enclosed in quotation marks. If no remark was entered, a null remark ("") is logged.
1.2 – Description
The CREATE CLASS command establishes a class. After a class is created, you can place any related set of element generations in that class by using the INSERT GENERATION command. The CREATE CLASS command does not automatically place any generations in the created class.
1.3 – Qualifiers
1.3.1 /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.
1.3.2 /OCCLUDE[=option,...]
Controls whether CMS selects the first instance of the specified object, or all instances of the specified object in the library search list. The options field contains one or more keywords associated with the name of the object. The options field can contain the following keywords: ALL--equivalent to CLASS CLASS (D) NOCLASS NONE--equivalent to NOCLASS You can specify either ALL, NONE, or the [NO]CLASS keyword. By default, CMS performs occlusion for all objects; that is, CMS selects only the first occurrence of a specified object. If you specify /OCCLUDE=NOCLASS, CMS creates a class in every library in the search list.
1.4 – Examples
(1) CMS> CREATE CLASS INTERNAL_RELEASE "for internal use only" %CMS-S-CREATED, class DISKX:[PROJECT.CMSLIB]INTERNAL_RELEASE created This command creates a class named INTERNAL_RELEASE. Once the class name is established, element generations can be placed in the class with the INSERT GENERATION command. (2) CMS> CREATE CLASS FTEST1,FTEST2,V1 "for external release" %CMS-I-CREATED, class DISKX:[PROJECT.CMSLIB]FTEST1 created %CMS-I-CREATED, class DISKX:[PROJECT.CMSLIB]FTEST2 created %CMS-I-CREATED, class DISKX:[PROJECT.CMSLIB]V1 created %CMS-S-CREATES, 3 creations completed This command creates the three classes FTEST1, FTEST2, and V1.
2 – ELEMENT
Creates one or more new elements in a CMS library from an existing file. Format: CREATE ELEMENT element-expression "remark"
2.1 – Restrictions
o If you specify the /NOTES qualifier, you must also specify the /POSITION qualifier on the same command line.
2.2 – 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.
2.3 – 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.
2.4 – Qualifiers
2.4.1 /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.
2.4.2 /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.
2.4.3 /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 (##).
2.4.4 /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.
2.4.5 /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.
2.4.6 /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.
2.4.7 /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.
2.4.8 /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.)
2.4.9 /REFERENCE_COPY
2.4.10 /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.
2.4.11 /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.
2.4.12 /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.
2.4.13 /BINARY
Controls whether CMS has to create an element of type binary or text. When you specify this qualifier, CMS creates the element in binary format irrespective of file properties. If you do not specify this qualifier, CMS decides on its own whether to create binary element or text element depending on file properties.
2.5 – 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.
3 – GROUP
Creates one or more empty groups. Format: CREATE GROUP group-name[,...] "remark"
3.1 – Command Parameters
group-name Specifies a name for the group. CMS reports an error if you specify an existing group or class name. (Group and class names must be unique.) However, if a previously used group or class name has been removed with the DELETE GROUP or DELETE CLASS command, you can reuse that name with CREATE GROUP. A group name can also be a list of group names separated by commas. Wildcards are not allowed. remark Specifies a character string for the creation remark of the group to be logged in the history file with this command. The remark is enclosed in quotation marks. If no remark was entered, a null remark ("") is logged.
3.2 – Description
The CREATE GROUP command establishes a group. After a group is created, you can place any related set of elements or groups in that group by using the INSERT ELEMENT or INSERT GROUP command. The CREATE GROUP command does not automatically place any elements or groups in the created group.
3.3 – Qualifiers
3.3.1 /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.
3.3.2 /OCCLUDE[=option,...]
Controls whether CMS selects the first instance of the specified object, or all instances of the specified object in the library search list. The options field contains one or more keywords associated with the name of the object. The options field can contain the following keywords: ALL--equivalent to GROUP GROUP (D) NOGROUP NONE--equivalent to NOGROUP You can specify either ALL, NONE, or the [NO]GROUP keyword. By default, CMS performs occlusion for all objects; that is, CMS selects only the first occurrence of a specified object. If you specify /OCCLUDE=NOGROUP, CMS creates a group in every library in the search list.
3.4 – Example
CMS> CREATE GROUP TIME_TST "files for time tests" %CMS-S-CREATED, group DISKX:[PROJECT.CMSLIB]TIME_TST created This command creates a group named TIME_TST. Once the group name is established, elements can be placed in the group with the INSERT ELEMENT command.
4 – LIBRARY
Creates one or more new CMS libraries in one or more existing empty directories. You can have only one CMS library in each directory. Format: CREATE LIBRARY directory-specification[,...] "remark"
4.1 – Restrictions
o You cannot specify both the /AFTER and the /BEFORE qualifiers on the same command line.
4.2 – Command Parameters
directory-specification Specifies one or more valid OpenVMS directories. Each directory must not contain any files. A directory that is to be used as a CMS library cannot be your current default directory. If you specify more than one OpenVMS directory, you must separate the directory specifications with commas. Wildcards are not allowed. remark Specifies a character string for the creation remark of the new library to be logged in the history file with this command. The remark is enclosed in quotation marks. If no remark was entered, a null remark ("") is logged in the history file.
4.3 – Description
The CREATE LIBRARY command builds CMS control files in a directory so that it can be used as a CMS library. After you have established a library with the CREATE LIBRARY command, you can issue CMS commands to manipulate the library. When you issue the CREATE LIBRARY command, your current CMS library is automatically set to the library or libraries specified. You can use CREATE LIBRARY only once on a library. You can create more than one library at a time by specifying the CREATE LIBRARY command with more than one directory specification. The directory specifications must be separated by commas. When you execute this command, CMS defines a logical name that begins with CMS$. These names are used by subsequent CMS commands. You should not define logical names beginning with CMS$ because this prefix is reserved for use by CMS.
4.4 – Qualifiers
4.4.1 /AFTER[=directory-specification]
Instructs CMS to insert new libraries into the existing library search list immediately following the existing specified directory. The specified directory must be in the existing library search list. If you omit the directory specification, CMS automatically adds the libraries (in the order you specify) to the end of the list. You cannot specify both /AFTER and /BEFORE on the same command line. If neither /AFTER or /BEFORE is specified, the CREATE LIBRARY command's library list supersedes any existing search list.
4.4.2 /BEFORE[=directory-specification]
Instructs CMS to insert new libraries into the existing library search list immediately in front of the existing specified directory. The specified directory must be in the existing library search list. If you omit the directory specification, CMS automatically adds the libraries (in the order you specify) to the front of the list. You cannot specify both /AFTER and /BEFORE on the same command line. If neither /AFTER nor /BEFORE is specified, the CREATE LIBRARY command's library list supersedes any existing search list.
4.4.3 /CONCURRENT (D)
Specifies whether elements in a library can have multiple reservations by setting the concurrent attribute on the library. Use /NOCONCURRENT to disallow multiple reservations. Use MODIFY LIBRARY to change this attribute on an existing library.
4.4.4 /CREATE_DIRECTORY
Instructs CMS to create a directory to contain the library if the directory does not already exist. /NOCREATE_DIRECTORY is the default.
4.4.5 /EXTENDED_FILENAMES
Used to create a CMS library that allows the use of extended file names. This qualifier is only available on OpenVMS V7.2 and later. Use /NOEXTENDED_FILENAMES to create a CMS library that does not allow the use of extended file names. /NOEXTENDED_FILENAMES is the default. Use MODIFY LIBRARY to change this attribute on an existing library.
4.4.6 /KEEP
Instructs CMS to not delete all versions of a file used to create a new element or generation. /NOKEEP is the default. Use MODIFY LIBRARY to change this attribute on an existing library.
4.4.7 /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. Use MODIFY LIBRARY to change this attribute on an existing library.
4.4.8 /LONG_VARIANT_NAMES
Used to create a CMS library that allows the use of long variant names. Use /NOLONG_VARIANT_NAMES to create a CMS library that does not allow the use of long variant names. /NOLONG_VARIANT_NAMES is the default. Use MODIFY LIBRARY to change this attribute on an existing library.
4.4.9 /REFERENCE_COPY=directory-specification
Specifies a valid OpenVMS directory to be used for reference copies of library elements. The directory cannot be a CMS library, nor should it be a subdirectory of a CMS library directory. If you use the CREATE LIBRARY command to create a search list of more than one library, you should specify a reference copy directory for each library in the search list. If you specify only one reference copy directory for more than one library, CMS creates one library for the entire search list, not one library for each library in the search list. Wildcards are not allowed. /NOREFERENCE_COPY is the default. Use MODIFY LIBRARY to change this attribute on an existing library.
4.4.10 /REVISION_TIME[=option]
Controls whether CMS uses the original file revision time or the file storage time when a file is retrieved from the CMS library. The options field can contain of the following keywords: ORIGINAL (D) STORAGE_TIME Use the ORIGINAL keyword to indicate that the original revision time of files placed in a CMS library should be restored unchanged upon their retrieval. This is the default behavior. Use the STORAGE-TIME keyword to indicate that the time when a file was stored in a CMS library (through a CREATE ELEMENT or REPLACE transaction) should be substituted for its original revision time upon retrieval. Use MODIFY LIBRARY to change this attribute on an existing library.
4.5 – Examples
(1) CMS> CREATE LIBRARY [RELEASE.CMSLIB] "follows development library" %CMS-S-CREATED, CMS Library DISKX:[RELEASE.CMSLIB] created This command creates a CMS library in the subdirectory [RELEASE.CMSLIB]. The library does not contain any elements yet. Subsequent CMS commands refer to the library contained in [RELEASE.CMSLIB] until the user logs out or issues a SET LIBRARY or another CREATE LIBRARY command. (2) CMS> CREATE LIBRARY [DOC.PRE.CMSLIB],[DOC.TESTA.CMSLIB], [DOC.FNL.CMSLIB] "creating doc lib" This example creates three CMS libraries in the subdirectories [DOC.PRE.CMSLIB], [DOC.TESTA.CMSLIB], and [DOC.FNL.CMSLIB], and sets the library search list to the three libraries, in that order.
