OOoBasic crash course: Working with files

OpenOffice.org's OOoBasic gives users tools to programmatically access and manipulate files. To see how that works, we'll create a simple macro that allows you to save text snippets from the current document in a plain text file. This macro can be used to store text fragments from multiple documents in one text file, or to save deleted passages in an external file in case you need them later.
