To provide a quick and easy visual reference the link to the project or project structure is distinguishable by the number of separator characters used. If there is no separator, the link is made to the project. A single separator character such as an exclamation mark after the project code (the first code) indicates the link type is a task (the link is to the project operational structure). Two separators placed after the project code mean that the link corresponds to a budget code (link to the project budget structure).
