Hi Timothy,

if you want to use Streams, you could also send #nextFloat:

    s := '2.14 -15' readStream.
    s nextFloat. "2.14"
    s nextFloat. "-15.0 "

(Shameless self-promotion: The SimulationMethodFinder [1] can help you to find such selectors - this is how I discovered this message just now.)

Other comments on your code: You only need to convert each value once into an integer if you store the result in a and b. Actually, you could even forego any conversion if you do not need validation since String>>#+ automatically handles that for you. You are using a lot of redundant brackets, only two pairs of them in your code are required. :-) Instead of string concatenation, you could also use String>>#format: again:

    outstring := '{1} {2} {3}' format: {a. b. a + b}.

Happy Squeaking!
