Notation Meaning
UPPERCASE LETTERS Uppercase letters represent keywords and reserved words; enter these
items exactly as shown.
lowercase italic letters Lowercase italic letters represent variable items that you supply.
Brackets [ ] Brackets enclose optional syntax items. A group of vertically aligned
items enclosed in brackets represents a list of selections from which you
can choose one or none.
Braces { } Braces enclose required syntax items. A group of vertically aligned
items enclosed in braces represents a list of selections from which you
must choose one.

Such a list, enclosed in either brackets or braces, is an alternative to a
vertical list for presenting selections.
Ellipsis ... An ellipsis immediately following a pair of brackets or braces indicates
that you can repeat the enclosed syntax items any number of times.
Spaces If a space separates two items, that space is required. If one of the
items is a punctuation symbol, such as a parenthesis or a comma,
spaces are optional.

above must be entered precisely as shown.
