The main path along the syntax diagram begins at the left with a keyword, and proceeds, left to right, to the vertical bar, which marks the end of the diagram. Paths that do not have an arrow or a vertical bar only show portions of the syntax.
The only part of a path that reads from right to left is a loop.
Paths that are too long for one line use continuation links. Continuation links are circled letters indicating the beginning and end of a link:
When you see a circled letter in a syntax diagram, go to the corresponding circled letter and continue reading.
