Logical values, constants, regular expressions, and abstracta

These important expression types are presented inline and also have a simple serif font.

If the value is null, the returned response will be false.

User entered values

Literal text that the user should type is presented in bold-serif.

At the password prompt, type MyPassword.

If the user should replace the value of a variable or placeholder, the replaceable text is in italics and set off with arrow brackets.

Within a code description, bar separators denote options from which the user must choose one.

% data = hdfread (start | stride | edge)

Optional parameters

[square brackets]

Within a code description, square brackets denote completely optional commands or parameters.

% sed [-n, -quiet]

Code variables

<arrow brackets>

Within a code sample, arrow brackets denote a variable that must be replaced with a valid value.
