The script, JUNCTION, is equivalent to part of the ISBL script SORTPOINT. It determines which nodes are numbered in the naUTilus numbering system. For a detailed discussion of this, see the discussion of SORTPOINT. The portion of SORTPOINT which is not done in the script JUNCTION is contained in the script OSORTPT.
The script SELJUNC is run in conjunction with JUNCTION (both from the same tool). SELJUNCTION allows the user to click on nodes which act as junctions with no ventilation. These are marked with a graphic (a red dot). So that should an error be made and junctions reset, an additional feature of this script is that it selects and deletes all old graphics on the view. If an error is made and the process needs to be rerun, the only graphics showing are the current junctions.
