In OpenOffice.org it is possible to protect parts (sections) of the document for editing. This means that you will have to enter a password before you can edit the content of the document.
However, you might want to be able to adapt a model document without the need of having to enter a password first. But on the other hand you want (parts of) the result document to be write protected. This can be achieved with the pragma function. With the pragma function you can set a password for the section you are currently in. This password needs only to be entered when editing this particular section in the result document.
