NOTATION CONVENTIONS
The following list summarizes the conventions for syntax notation
in this manual.
Notation Meaning
UPPERCASE Uppercase letters represent keywords and reserved
LETTERS words; enter these items exactly as shown.
italics 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.
Vertical A vertical line separates alternative syntax items
line | in a horizontal list. Such a list, enclosed in
either braces or brackets, 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 A percent sign precedes a number that is not in
sign % 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.)
I/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.
