Conventions used in this manual

Examples of messages and prompts written by the program, as well as examples of user typed input are displayed in `typewriter type style`.

User typed input is usually displayed in the colour `blue`.

Messages and variables created by the program are usually displayed in the colour `orange`.

Curly brackets, `{ }`, enclose parameters that are optional and/or have default values, and indicate that it is not necessary to enter these parameters.

Vertical bars, `|`, separate choices for command parameters.

Curly brackets and vertical bars should not be entered with commands.

Parentheses, `( )`, besides being used in mathematical expressions, also enclose formats.

The back slash, \ , separates a command from a command qualifier or a parameter from its qualifier.

Literal quote strings can be delimited by the opening quote, ```, and the single quote, `'`, or by the single quote at the beginning and the end, or by the double quote, `"`, at the beginning and the end. For example, ``ABC'`, `'ABC'`, and `"ABC"` are all valid literal quote strings.

Parentheses, the back slash and quotes must be included where indicated.
