1.3 Typographical Conventions

This book uses the following typographical conventions:

• Slice source code appears in monospace.

• Programming-language source code appears in monospace.

• File names appear in monospace.

• Commands appear in monospace bold.

Occasionally, we present copy of an interactive session at a terminal. In such cases, we assume a Bourne shell (or one of its derivatives, such as ksh or bash). Output presented by the system is shown in monospace, and input is presented in monospace bold, for example:

$ echo hello
hello

Slice and the various programming languages often use the same identifiers. When we talk about an identifier in its generic, language-independent sense, we use monospace. When we talk about an identifier in its language-specific (for example, C++ or Java) sense, we use monospace.
