You can access online help for any placeholder in the LSE
    templates for SQL. To obtain this help while you are editing,
    position your cursor on the placeholder, then press the PF1 and
    PF2 keys in succession.

    The templates include some placeholders for low-level syntax.
    While these topics are essential to SQL, they are so general as
    to not be applicable at top-level help. This topic, General_SQL_
    Terms, serves as a location for the low-level help topics that
    LSE requires.
