RandomFile seek method

[Claude Rouleau]

I am revisiting RandomAccessFile and found that the argument for the seek method is a long (64 bytes integer). The documentation says that it is the offset position, measured in bytes from the beginning of the file.
Since there is no way to specify another starting point I concluded that the maximum lenght of a Random file is (2 power 63) -1.
Do I am right?
