talzamir is right. If no symbol is placed between digits, they read as a single number. But I'm not sure why that's ambiguous - what would you do with the numbers with no symbol between them if they are distinct numbers and not just digits? For example, what does the expression 1 2 3 = 2002 even mean?

For under Windows, I personally prefer ZX Spin, but it's very much a matter of taste.
