/PATTERN
       /NOPATTERN (D)

    Enables or disables special interpretation of wildcard patterns
    in a search string. Use the SET SEARCH command to specify the
    style of wildcard patterns (VMS, ULTRIX or TPU).

    For details of the pattern styles use the command HELP FEATURES
    PATTERNS.

    When you specify the /NOPATTERN qualifier (or when it is the
    default), special interpretation of wildcard patterns in the
    search string is disabled.
