## Syntax

Within the individual reference articles for each statement, the syntax is described using the following conventions:

* **`bold`** for keywords
* *`italics`* for arguments
* Square brackets for optional keywords and arguments `[`**`like`***`this`*`]`
* Vertical pipe for alternative keyword options **`just|exactly`** as shown 
* Ellipses for a variable length list of arguments: *`Column1`* `...` *`ColumnN`*
