Like all words, 'script' and 'program' mean whatever you arbitrarily feel like they should mean in the moment. There are no lines until there is use, and what lines may exist during that use can only be determined at the time of use. And at the next time of use, things could be completely different. Some times there may be lines, other times there may not be. If you need to draw lines between two things, 'script' and 'program' may be tools you can use to communicate that. Or maybe not. Indeed, there is a lot of guess work involved in communication, and it can take some trial and error to find the right tools to accurately reach the intended audience.
