(.RTE) - extracts attributes related to SWAT routing variables
          .rte$sub%i%chl2 - channel length from the outlet of a subbasin
                            to the outlet of the entire basin
          .rte$sub%i%chss - average channel slope for the points described
                            above

The (.SUB) button requires inputs defined in the (.BSN) button, therefore, the (.BSN) button must be executed first.

The (.PCP), (.TMP), (.SOL), and (.RTE) buttons require inputs defined in the (.BSN) and (.SUB) buttons, therefore, the (.BSN) and (.SUB) buttons must be executed first.  The order of execution of the (.PCP), (.TMP), (.SOL), and (.RTE) buttons does not matter, they may be executed in any order.
