XF allows saving selected procedures into a shape archive. This makes the procedures publically available, and allows the access to the development history of this procedure. This feature is accessed from the Programming dialog window. The buttons (Save) and (Load) are used to save and load the procedures. Saved procedures are stored with version numbers, showing the development of this procedure. If ShapeTools are not installed, the procedures are saved as plain files, without any additional information. In this case only one version of the procedure exists.
