Forums Scripts & Popups Help with an IF statement

I am familiar with the IF statement but having to go through a list, like this I dont think would be the best way to do it, any advice?

elseif ($5 == LANGUAGE) {
var %l = $4-
if ($4 == EN) %l = English
if ($4 == NL) %l = Dutch
if ($4 == JA) %l = Japanese
if ($4 == DE) %l = German
if ($4 == AR) %l = Arabic
if ($4 == FR) %l = French
if ($4 == ES) %l = Spanish
echo $2 11• Language11: %lang
}
