Hi Ed,

(I saw your acknowledgement to Logan)

Here's another:
...............

FNAME = 'test.bin'

class Files
  @@file = nil
  @@code = []
  @@address = 0
  @@offset  = 0

  def Files.read_file
    File.open(FNAME, 'rb') do | @@file |
      while @@address < 65536 and (@@byte = @@file.getc)
       @@code.push(@@byte)
       @@address += 1
      end
    end
  end

  def Files.readCodeByte(index)
    @@file or read_file
    @@code[index-@@offset]
  end

  def Files.setOffset(anoffset)
    @@file or read_file
    @@offset = anoffset
  end
end
