I cant tell by the code you gave, however I suspect you want to know this:

Get returns a sequence of 2 element.
The first element is the succes/error value, the second the result value.

in = get (0)

-- Now type: "Hello, dear!"
if in[1] = GET_FAIL then
    puts (1, "Whatever you typed, it didnt make sence for me!\n")
elsif in[1] = GET_EOF then
    puts (1, "You typed too little, why not finish it before pressing
enter!\n")
elsif in[1] = GET_SUCCES then
    puts (1, "Now, that *does* make sense!\n")
    print (1, in[2])
end if

-- in[2] only contains the value whenever in[1] = GET_SUCCES which is
whenever we could make a number out of the input.

Remember that Euphoric input using print () and get () is pretty flexible.
If the user enters: { 1, 2, 3} it will return {1, 2, 3}
So be aware, the user is also allowed to define whole sequences, or use
heximal values..

There is a very nice demo program that comes with euphoria that shows
exactly how to use get () and print ().
