I have a shapefile (either polygon or polyline) that I need to convert to an "Area Data" .dat file to use with another program (it's already older, it says it wants "ArcInfo Format").
I've tried Googling and playing around with the different export functions, but so far I haven't had any luck.
I'm fairly new to working with ArcGIS. I have ArcGIS Desktop 10.5 and the other program I need to load the map to is a very specialized program for theodolite tracking, Pythagoras (http://www.cetaecoresearch.com/research-software-pythagoras.html).
