Asif, you need to RTFM (read the friendly manual)...
include get.e
object input
atom value1, value2, value3, average, error_code --why so complex
example??????
This is just establishing that the variables named above will hold atom
values... not complex at all!
[snip snip]
while error_code != 0 do
input = get(0)
error_code = input[1] --What is this??? What is [1]
end while
You can figure this out by reading the information on get().
name = input[2] --What is this?? what is [2]
Simple sequence subscripting. The code is setting the variable "name" to
equal the second element of the sequence "input". RTFM regarding sequences.

That's what I intended it to do. Once it has successfully
read a Euphoria atom or sequence it will return the
value. It doesn't care that the next character in the input is
bogus.
However there is a thorny issue regarding get()
that I might as well mention.
* Warning: tedious detail ahead *
The manual states that you must have at least one
whitespace character between "top-level" objects
in the input stream. This is because get() typically needs to read
one more character beyond the end of an atom, and
it can't "unget" the character properly because you might switch to reading
some other input stream with your next call to get(), making the ungotten
character invalid. Each call to get() must therefore start with a fresh
getc(), ignoring any ungotten character from before.
This problem could be resolved by somehow associating
an ungotten character with every input stream, but I didn't bother to set up
anything like that.
