1. 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?

2. Re: data structures in EU
While showering, I realized that an embarrassingly easy solution to my
data structure question is to define a function which takes the data
elements and concatenates them into the required sequence for the record
definition. A similar function would accept the record sequence and pars
it into the required fields.
I see how I can do the bit-fiddling by using bits_to_int and int_to_bits
in the functions mentioned above. Are there better ways?
