I have been searching for a list of functions for LibreOffice Basic. Thanks
Thanks. Exactly what I was looking for.
You can use this help topic - The LibreOffice Help
But if you are interested not only in the list of functions, but in the way they are used to solve current problems, then I recommend you the books of Andrew Pitonyak.
Pay particular attention to this book. It is very simple to use: find your current problem in the table of contents and get a solution.
