Each course and component is supplied with a unique code which contains a maximum of 15 characters. The code column cannot be blank. In order to avoid conflicts, courses and components cannot have any code in common. The code is used as a shortcut to all other information associated with it. It is a good hint to select its first characters so that it informs the user as much as possible about the content associated with it, and it also helps the user to identify the right course or component when it is sorted by code. References to components and courses are often performed on the screen with the help of the code, when there is not enough space to show the name. When printing timetables or other reports, the user often has the option to show either code, name or both.
In case you want to reorganise or rename several codes, you can use Clipboard and code conversion table in selection Tools|Code conversion... and you can also automatically change the codes to upper or lower case in Options|Other. If you have selected Tools|Sort automatically, adding of new components or courses reorganises them again according to non-decreasing order.
If codes are required to be sorted first by categories and then by codes, select first Tools|Sort first by categories. This usually selected in case of components, since it groups all components of the same category.
