Subject: Not initialized

The class below seems to do exactly what I want it to do provided 
Files.read_file is called first.
But it would be nice not to have to call Files.read_file externally at all 
and have the other two methods automatically call it once, the first time 
either of them is used.
So far I've not been able to do this without getting "uninitialized class 
variable" errors. Is there a simple way to do it?
I've only been learning Ruby for two days so it's quite possible I've missed 
the obvious.

class Files

 def Files.read_file

  @@file = File.open("test.bin","rb")

  @@code = []

  @@address = 0

  while @@address < 65536 and (@@byte = @@file.getc) != nil

   @@code.push(@@byte)
   @@address += 1

  end

  @@file.close

 end

 def Files.readCodeByte index
  return @@code[index-@@offset]
 end

 def Files.setOffset anoffset
  @@offset = anoffset
 end

end
