Copies one or more existing groups to form one or more new
groups. If you copy a group to the same library, the new
group must have a different name. The COPY GROUP transaction
preserves all group attributes and inserts elements and groups
that belong to each input group. The elements to be inserted
into the new group must already exist in the target library.
Format:
COPY GROUP old-group-expression new-group-name "remark"
1 – Command Parameters
old-group-expression
Specifies one or more existing groups to be copied. If you
specify more than one group to be copied, you must use a
wildcard character for the new group name. An old group
expression can be a group name, a wildcard expression, or a
list of these separated by commas.
new-group-name
Specifies the name for the new group. The name cannot be the
same as any existing group name in the target library. Wildcards
are allowed. If you specify more than one group with COPY GROUP,
you must use a wildcard character for the new group name.
remark
Specifies a character string for the creation remark of the new
group to be logged in the history file with this command. The
remark is enclosed in quotation marks. If no remark was entered,
then the remark from the old group is used for the creation
remark of the new group, but a null remark ("") is logged in
the history file.
2 – Description
The COPY GROUP command uses an existing library group to copy
and create a new group in the same library or in another library.
The original group is left unchanged. The group attributes are
copied in full and an identical set of elements and groups are
inserted into the new group. The elements to be inserted into
the new group must already exist in the target library.
CMS must be able to create one new group for each old group.
When you use wildcards, or a comma list in the input group
specification you must specify a wildcard ("*") as the output
group specification.
3 – Qualifiers
3.1 /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.
3.2 /LIBRARY[=directory-specification]
Identifies a valid CMS library that is the location of the group
specified by the old-group-expression parameter. When you
specify an alternative library, the new-group-name parameter is
optional. If you do not specify a value for /LIBRARY, the current
CMS library is used.
3.3 /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.
3.4 /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 GROUP
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.
4 – Example
CMS> COPY GROUP INIT_GROUP INITX_GROUP "experimental version"
%CMS-S-COPIED, class DISKX:[PROJECT.CMSLIB]INIT_GROUP copied
to INITX_GROUP
This command creates a new group named INITX_GROUP in the same
library as the old group.
