Command Syntax
Syntax and Commands
2Ć10
The syntax diagrams in this manual use the following symbols and notation:
H Circles and ovals contain literal elements. You must send most elements
exactly as shown. The diagrams show command mnemonics in both
upper and lower case to distinguish between complete and abbreviated
spellings. These elements are not case sensitive and you can omit the
lower case portion of the mnemonic.
H Boxes contain the defined elements described earlier in this section, such
as <NR3> or <QString>.
H Elements are connected by arrows that show the allowed paths through
the diagram, and thus the orders in which you can send the elements.
Parallel paths show that you must take one and only one of the paths. A
path around a group of elements shows that those elements are optional.
Loops show elements that you can repeat.
Figure 2Ć3 shows the structure of a few typical syntax diagrams.
