Although DCL preserves the case of extended file names, wildcard
    matching is case blind.

    When you perform a search operation with wildcards it continues
    to match only against the corresponding character in the same
    part of the target specification. The following table contains
    examples of some wildcard searches.

    The
    pattern...     matches...             ...but doesn't match
