I would suggest stripping the data files with some handy stripper (you or I can write a quickie in C) and keeping just the ascii, then look at how the data is represented & try to parse it into proper format. Several packages can do such parsing, but it is often simpler to write your own than try to decipher their (often) cryptic macro instructions & formats! Good luck! Misha.
