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

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.

2 - /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 - /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.

4 - /REMOVE_CONTENTS

    Controls whether CMS removes generations of elements from the
    specified class prior to deleting the class. When /REMOVE_CONTENTS
    is specified CMS displays an informational message for each element
    generation that is removed from the class.
