- It's just for programmers' safety. When this magic number is not present in the
- parameter list for the XBios call, you might have called the Flopfmt() function
- by accident, instead of calling, say, Floprd(). Without the magic number's
- safety, off goes your data. With it, XBios returns an error code.
