It looks like you've gotten several answers, but based on your requirements,
I also to suggest  using print() and get().  It's quick and easy, and hard ato
break.

--  tested code:
include get.e
object numbers
 numbers = {1.23, 3.14159, 6, 8, -23.5, 12.99}

atom fn
fn = open("my.dat","w")
print(fn, numbers)
close(fn)

fn = open("my.dat","r")
numbers = get(fn)
close(fn)
if numbers[1] = GET_SUCCESS then
   numbers = numbers[2]
else
  puts(1,"ERROR READING FILE")
end if
? numbers

If you plan to store lots of strings in your files, you really need to
downloading Gabriel Boehme's PRINT.E - this small library causes the print()
function to write text in plain, human readable form, while still being
readable by Euphoria's get() function.

I have been using this method for many months in several commercial programs
without any  problems These programs typically read (modify) and write files of
about half a meg hundreds of times each day.

By the way, these files will be plain text, so probably NotePad or similar
would be just fine for viewing them.
