By allowing conv36 to concatenate multiple files and placing tape marks between each, it can be used to create a tape. Adding -Bn makes it possible to divide the tape files into records. With these updates, conv36 can do the job of tracks.
Now that conv36 has become so versatile, it irked me that it would stop at a logical end of tape mark even if there are more data after it. So I fixed that too.
