1.2.2 Symbols used in syntax

|

In syntax explanations, a vertical bar separates multiple items, and has the meaning of OR. For example:

A|B|C means A, or B, or C.

[ ]

In syntax explanations, square brackets indicate that the enclosed item or items are optional. For example:

[A] means that you can specify A or nothing.

[B|C] means that you can specify B, or C, or nothing.

{ }

In syntax explanations, curly brackets indicate that only one of the enclosed items is to be selected. For example:

{A|B|C} means only one of A, or B, or C.

...

In syntax explanations, ... indicate that description is omitted.

ABC... means that there is a description after ABC, and this description is omitted.

Alternatively, in syntax explanations, an ellipsis indicates that the immediately preceding item can be repeated as many times as necessary. For example:

<Property>...means that you can specify as many properties as necessary.

< >

In syntax explanations, angle brackets indicate a variable.

For example:

<Property> means that the user enters a property name or a property name is displayed.

<File name> means that the user enters a file name.
