Is this possible? My idea for this would be via a /file datum that stores the file name like a /savefile does. The main reason I ask for this is because of the Binary IO library, which allows reading/writing of binary files directly from DM (using a DLL). However, due to its reliance on filenames, and the fact that there is no way to get the filename from a file 'as file' argument to verbs/input(), it cannot take advantage of the file dialog used by the 'as file' argument. I'm not sure if this is easy or hard to implement, but it'd be useful for interacting with the Binary IO library, even if for just single-player games.
