When new C# syntax is introduced, the usual approach will be to give both specific examples and general templates. In general templates for C# syntax the typeface indicates the the category of each part:
| Typeface | Meaning |
|---|---|
| Typewriter font | Text to be written verbatim |
| Emphasized | A place where you can use an arbitrary expression. |
| Bold | A place where you can use an arbitrary identifier. |
| Normal text | A description of what goes in that position, without giving explicit syntax |
An attempt is made with the parts that are not verbatim to be descriptive of the use expected.
We will use these conventions shortly in the discussion of function syntax, and will continue to use the conventions throughout the notes.
