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