Syntax Diagrams
The syntax of each command and query is explained by both syntax diagrams
and BNF notation. Figure 2–5 shows some typical syntax diagram structures.
The syntax diagrams are described by the following symbols and notation:
H
Oval symbols contain literal elements, such as a command or query header
and a nonquoted string argument.
H
Circle symbols contain separators or special symbols, such as (:), (,), and (?).
H
Box symbols contain the defined element, such as <NR1>.
H
Arrow symbols connect elements to show the paths that can be taken through
the diagram and, thereby, the order in which the elements can be sent in a
command structure.
H
Parallel paths show that only one of the paths can be taken in the command.
See diagram 1 in Figure 2–5.
H
A loop around an element(s) shows the element can be repeated. See
diagram 2 in Figure 2–5.
H
A path around a group of elements shows that those elements are optional.
See diagram 3 in Figure 2–5.
NOTE
. The unit and SI prefix that can be added to decimal numeric arguments
are not described in the syntax diagram. See Unit and SI Prefix on page 2–7.
