I''m trying to use split method and here is my sample code.When I use
irb I gett following output
irb(main):001:0> result = "OK:1234"
=> "OK:1234"
irb(main):002:0> result.split('':'')
=> ["OK", "1234"]
irb(main):003:0> result[1]
=> 75
I am not able to figure out when am trying to access 2nd element of
the result array, why does it return "75", instead of
"1234".
Am I missing something over here? Any help is much appreciated
Thanks,
Sushil

Use split with a bang intead (split!) if you wish to change the variable itself. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thanks for your help. I was not assigning the result of split. I know this is simple Ruby question, but I was looking for a quick help and that'' why posted my question in this group. I am not a member of "Ruby" group.
