Drawback of that method is that there is no editing possible during input=
=2E
I myself mostly stick to the following:

include get.e

function input(sequence prompt)
-- simple numeric input routine
object number
    puts(1, prompt)
    number =3D get(0)
    number =3D number[2]
    return number
end function    -- input

function input_string(sequence prompt)
-- simple string input routine
sequence string
    puts(1, prompt)
    string =3D gets(0)
    return string[1..length(string)-1]
end function    -- input_string

Certainly these functions are not foolproof either. Add your own validity=

tests and maybe a clear_to_end_of_line() and some loops to check the inpu=
t
and ask for new input if necessary.
