Sljedeće opisuje osnovno korištenje varijable u LibreOffice Basicu.
LibreOffice Basic provides tools to help you structuring your projects. It supports various "units" which enable you to group individual SUBS and FUNCTIONS in a Basic project.
Libraries serve as a tool for organizing modules, and can either be attached to a document or a template. When the document or a template is saved, all modules contained in the library are automatically saved as well.
A library can contain up to 16,000 modules.
A module contains SUBS and FUNCTIONS along with variable declarations. The length of the program that can be saved in a module is limited to 64 kB. If more space is required you can divide a LibreOffice Basic project among several modules, and then save them in a single library.
Dialog modules contain dialog definitions, including the dialog box properties, the properties of each dialog element and the events assigned. Since a dialog module can only contain a single dialog, they are often referred to as "dialogs".
