Libraries, Modules and Dialogs
The following describes the basic use of libraries, modules and dialogues in LibreOffice Basic.
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 organising 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.
Dialogue modules contain dialogue definitions, including the dialogue box properties, the properties of each dialogue element and the events assigned. Since a dialogue module can only contain a single dialogue, they are often referred to as "dialogues".
