Courier Bold, for example:
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
Lucida Sans Typewriter. When we talk about an identifier in its language-specific (for example, C++ or Java) sense, we use
Courier.
