VX4792 User Manual
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 non-quoted string argument; command name, query name, and
nonquoted string argument are abbreviated
H Circle symbols contain separators or special symbols such as (:), (,), and (?)
H Box symbols contain the defined element
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 one and only one of the paths must be taken in the
command (see the top diagram of Figure 3–2)
H A loop around an element(s) shows the element can be repeated (see the
middle diagram)
H A path around a group of elements shows that those elements are optional
(see the bottom diagram.)
NOTE. The unit and SI prefix that can be added to decimal numeric arguments
are not described in the syntax diagram. See Units and SI Prefix on page 3–4.
