just a short explaination: echo contatenates nothing, 
it *immediately* generates the requested output
plus arguments are evaluated before they are passed 
to a function (lets assume "echo" is a function for
now)

so before "echo" is called the argument string is 
evaluated, for this Translate() is called, which
itself contains an echo call which is executed first now

what you wand is "return $R;" instead of "echo $R;"
in Translate()
