VMS Help CMS, SHOW, CLASS  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Displays information about one or more classes in a CMS library.

       Format:

          SHOW CLASS  [class-expression]

1 - Command Parameters

 class-expression

    Specifies one or more classes to be listed. If you do not specify
    a class name, CMS lists all classes in the library. A class
    expression can be a class name, a wildcard expression, or a list
    of these separated by commas.

2 - Description

    The SHOW CLASS command lists the names of all established classes
    in alphabetical order, along with the associated creation remarks.

3 - Qualifiers

 3.1 - /APPEND

    Controls whether CMS appends the command output to an existing
    file, or creates a new file. If you specify /APPEND and the output
    file does not exist, CMS creates a new file. If you do not provide
    an output file specification (see the description for /OUTPUT),
    the output is appended to SYS$OUTPUT.

 3.2 - /BRIEF

    The /BRIEF qualifier displays only class names.

 3.3 - /CONTENTS

    Controls whether CMS identifies the element generations that
    belong to each class. If you specify /CONTENTS, CMS displays the
    class name and the creation remark, along with the element name
    and generation number for each generation in the class.

 3.4 - /FULL

    The /FULL qualifier displays the name, creation remark, and
    read-only attribute (if established) for each class.

 3.5 - /INTERMEDIATE

    The /INTERMEDIATE qualifier displays the name and creation remark
    for each class.

 3.6 - /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.

 3.7 - /OUTPUT[=file-specification]

    Directs CMS to write output to the specified file, except for any
    warning and error messages, which are written to SYS$OUTPUT and
    SYS$ERROR. CMS creates a new file if you do not specify /APPEND.
    If you omit the /OUTPUT qualifier (or if you specify /OUTPUT
    but do not provide a file specification), CMS directs output to
    the default output device (SYS$OUTPUT). If you omit either the
    file name or the file type component, CMS supplies the missing
    component from the default specification.

4 - Examples

    (1) CMS> SHOW CLASS

        Classes in CMS Library DISKX:[RELEASE.CMSLIB]

        INTERNAL_RELEASE   "for internal use only"
        MESSAGETEST     "filter evolution checks"
        PASCAL_CLASS    "PASCAL tests"

      This command displays the class name and the creation remark
      for each class in the library.

    (2) CMS> SHOW CLASS/BRIEF

        Classes in CMS Library DISKX:[RELEASE.CMSLIB]

        INTERNAL_RELEASE       MESSAGETEST         PASCAL_CLASS

      This command limits the output to class names only.
