Most Lotus applications allow you to create pre-compiled LotusScript objects, known as .LSO files. These files can then be used by other scripts by including a "Use" statement that references the compiled object. The LSO files are the compiled output from the LSX Toolkit.
The TOOLKIT is available at http://www.lotus.com/developers/devbase.nsf/homedata/homelsx. The Toolkit guide is online at: http://www.notes.net/notesua.nsf/8a96f3d2526c8afe8525665d006c9e30/1a71882e25ee82a2852567cc004b1514?OpenDocument.
