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.
