Using the "." Operator

Using the "." operator

Another cool Perl trick is the use of the "." operator that "appends" a value to an already existing scalar variable. Thus, the following code would print out "Selena Sol":

$name = "Selena" . " Sol"; 
print "$name";

An alternative shorthand for appending to scalar variables is using the ".=" operator. For example, the following code does the same thing as the code above.

$name = "Selena"; 
$name .= " Sol"; 
print "$name\n";
