Throughout the documentation, text printed in this typeface represents verbatim communication with the computer: for example, pieces of C text, commands to the operating system, or responses from the computer. In examples, text printed in this typeface is not to be used verbatim: it represents a class of items, one of which should be used. For example, this is the format of one kind of compilation command:

hcl source-file

This means that the command consists of:

- The word hcl, typed exactly like that.
- A source-file: not the text source-file, but an item of the source-file class, for example ‘myprog.c’.

Whenever commands to and responses from the computer are mixed in the same example, the commands (i.e. the items which you enter) will be presented `in this typeface`. For example, here is a dialogue with the computer using the format of the compilation command given above:

    c:\crossworks\examples>hcl -v myprog.c
    CrossWorks MSP430 Compiler Driver   Release 1.0.0
    Copyright (c) 1997-2004 Rowley Associates Ltd.

The user types the text hcl -v myprog.c, and then presses the enter key (which is assumed and is not shown); the computer responds with the rest.
