What are you expecting the "x:y" statement to do? I ask because I'm not
familiar with that syntax, and ":" doesn't appear alone on any list of
operators I've seen. Otherwise I only know it as the second operator of
the ternary operator ?:
In any case, what again are you trying to accomplish? There's probably
a better way that doesn't have a syntax error.

Sorry I forgot to post this.
I was doing that above the summary in the code, above the output.

Got it - in your code, you typed ":", while the example uses ";".
And to expand a bit on what I typed below, the ":" is used to indicate
symbols, like ":x". So when you had the typo "|y:x|", ruby thinks
there's two items there - "y" and ":x".

I have done that and it says:

3.times do |y;X|
test6.rb:5: syntax error, unexpected tSTRING_BEG, expecting kDO or '<'

I realised that mistake of using : instead of ;
But I am still getting an error

As the page notes, this was introduced in Ruby 1.9.1. I'm guessing you are using an older version.

One other note: you have an uppercase X instead of a lower case x.

I looked at the code there was no uppercase x, I am baffled.

Yes, I saw the same error in 1.8.6 but not in 1.9.2.

I think that you are still using 1.8.6 when you get this. Look at the
value of RUBY_VERSION. I see the exact error message in 1.8.6.

Works fine on 1.8.7.
