There are two <span class="type"><a href="language.types.string.html" class="type string">string</a></span> operators. The first is the
concatenation operator ('.'), which returns the concatenation of its
right and left arguments. The second is the concatenating assignment
operator ('<em>.=</em>'), which appends the argument on the right side to
the argument on the left side. Please read <a href="language.operators.assignment.html" class="link">Assignment
Operators</a> for more information.
