The first line of the file, for example, looks like this:

"Montanas","","","","","IV/25",0,0,0,0,0,0,0,0,18,90,1,5,0,0,0,0,0,0,1,5,0,0,0,0,0,0,20,100

This context belongs to the physiographic zone "Montanas", there is no subcommunity, nor group, site type or structure. The operation is "IV/25". There are 0 prismatic blades (0%), 0 polyhedral cores (0%), 0 bifacial points (0%), 0 bifacial thinning flakes (0%), 18 general debitage (90.0%), 1 scraper (5.0%), 0 notched flakes (0%), 0 denticulates (0%), 0 drills (0%), 1 flake core (5.0%), 1 chopper (0.5%), 0 chopping tool (0%) and 0 eccentrics (0%), with a total of 20 artifacts (100.0%). The quotation marks around "Montanas" and "IV/25" indicate that these variables are alphanumeric and "" indicates the absence of data.

The last (112th) line is:

"Vega","Principal Group","10L-1","5","10L-22A","44/3",0,0,0,0,0,0,0,0,1,50,1,50,0,0,0,0,0,0,0,0,0,0,0,0,0,0,2,100

Which indicates the physiographic zone "Vega", subcommunity "Principal Group", group "10L-1", site type "5", structure "10L-22A". Belongs to the operation "44/3". There are 0 prismatic blades (0%), 0 polyhedral cores (0%), 0 bifacial points (0%), 0 bifacial thinning flakes (0%), 1 general debitage (50.0%), 1 scraper (50.0%), 0 notched flakes (0%), 0 denticulates (0%), 0 drills (0%), 0 flake cores (0%), 0 choppers (0%), 0 chopping tool (0%) and 0 eccentrics (0%), with a total of 2 artifacts (100.0%). The quotation marks around "Vega" and "Principal Group" indicate that these variables are alphanumeric and "" indicates the absence of data.
