data structures in EU

The ref manual states that "the exact layout of a data structure does 
not have to be declared in advance". But can I do so if it serves my 
purpose?
I would like to declare a "record_layout" consisting of { 
"16_text_bytes", 4-byte_integer}. I will put a number into the first 
three bytes of the integer and do bit-fiddling with the 8 bits of the 
last byte. I would like to address the pieces individually and then move 
the structure as a whole (and vice-versa). I can see how to do this with 
offsets into a buffer allocated in RAM, but are there more direct 
methods provided by Euphoria?
