Assuming by location line you mean finish face exterior / core face exterior / center / core center/ core face interior / finish face interior?
The parameter is actually a number value not a string, so you need a bit of a decoder to sort it out. Clearly asking people to remember that 0 means centerline was a bit much, so the parameter is usually viewed as the text you’re likely looking for to avoid confusion. But if you want to get/set parameter values in the usual way using the API, you need to work with the actual storage types not the results after they are passed though the decoder.
Hopefully this can serve as a bit of a decoder ring. Sorry I already ate all the cracker jacks…
