Separators can be anything reasonable. When eol is encountered, it will
read zeros. And errors are not handled: any non-numeric will yield zero.
Ah, in other words it is a toy, utterly unsuitable for serious use by anyone
who cares about data validity and error checking, only suitable for
teaching bad habits to beginners.
So, how does Python differ? From what I've seen, you have to /write/ the
validation code (as I said in my last post). ANY language can do that too!
And the eol-handling behaviour is deliberate. If you want to read UP TO
three numbers but only two are entered on a line, some languages will
keep pestering you until you've entered that third number.
