The following list summarizes the conventions for syntax presentation in this manual.
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, several, 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.
Vertical line | A vertical line separates alternative syntax items in a horizontal list.
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.
Percent sign % A percent sign precedes a number that is not in decimal notation.
% indicates octal notation. %B indicates binary notation. %H indicates
hexadecimal notation. %D at the end of a hexadecimal value denotes
double precision. %F at the end of a hexadecimal value denotes a fixed
numeric constant.
Pound sign # A pound sign precedes a number in decimal notation.
I and O In procedure calls, input parameters (those passing data to the called
procedure) are followed by an I; output parameters (those that return
data to the calling program) are followed by an O.
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.
Punctuation Parentheses, commas, semicolons, and other symbols not described
above must be entered precisely as shown. Quotation marks around
any symbol indicate that it is not a syntax descriptor but a required
character, and you must enter it as shown.
