TEST/MATCH may be used to test wildcard and glob matching, such
    as in a mapping pattern.

    When invoked, TEST/MATCH prompts for a pattern and then for a
    target string to compare against the pattern, and will output
    whether or not the target string matched and if it did match,
    which characters in the target string matched which wildcard or
    glob of the pattern. TEST/MATCH will loop, prompting for input,
    until exitted with a CTRL/Z.
