keyword-list
    Indicates the search mode settings. The keywords are as follows:

    AUTO_REVERSE
    NOAUTO_REVERSE

    Specifies whether or not LSE searches in the current direction
    only, or searches in the opposite direction if the string is not
    found in the current direction. The initial setting is NOAUTO_
    REVERSE.

    CASE_SENSITIVE
    NOCASE_SENSITIVE

    Specifies whether or not the SEARCH command matches case exactly
    or is insensitive to character case. The initial setting is
    NOCASE_SENSITIVE.

    DIACRITICAL_SENSITIVE
    NODIACRITICAL_SENSITIVE

    Specifies whether or not the SEARCH command matches characters
    with diacritical markings exactly or is insensitive to diacritical
    markings. The initial setting is DIACRITICAL_SENSITIVE.

    PATTERN=VMS
    PATTERN=ULTRIX
    PATTERN=TPU

    Specifies either VMS, ULTRIX or TPU style patterns for the
    SEARCH/PATTERN and SUBSTITUTE/PATTERN commands. The initial
    setting is VMS. For details of the pattern styles use the command
    HELP FEATURES PATTERNS.

    SPAN_SPACE
    NOSPAN_SPACE

    Determines whether LSE matches blanks in the search string exactly
    (NOSPAN_SPACE) or allows each blank to match sequences of one or
    more characters containing blanks and tabs and, at most, a single
    line break (SPAN_SPACE). The initial setting is NOSPAN_SPACE.
    Not applicable to SEARCH/PATTERN and SUBSTITUTE/PATTERN commands.
