For i18n, you may need to replace the "\n" with "\r\n". The "\n" represents the newline character. BTW - You'll need to take the underscore out of your name and add a space in its place. There aren't many rules around here, but the naming policy is one of them. It looks like you've gotten by this long, though.
In the example above, I've taken a series of strings and concatenated them using the "+" operator. Is this what you mean by "more than one line in a String"? Also, I added the carriage-return escape character (\n) to the String. If you were to send this String to your screen, it would look like this: I would like to know if more than one line can be present in a String. Is so plz gimme an example. Is that what you meant by having mulitple lines?
