Identifiers can be any length. <abbr title="Digital Art Zone">DAZ</abbr> Script identifiers match the regex pattern <strong>[_A-Za-z][_A-Za-z0-9]</strong>*, which if you&#039;re unfamiliar with regular expression, means that the character occupying the first position of an identifier can be one of the following (note the lack of numbers): </p> <p> <strong>_ A B C D E F G H I J K L M N O P Q R S T U V W X Y Z a b c d e f g h i j k l m n o p q r s t u v w x y z</strong> </p> <p> And the characters that can occupy any subsequent positions in an identifier include those above plus the following, any number of times: </p> <p> <strong>0 1 2 3 4 5 6 7 8 9</strong> </p> </div> <h2 id="reserved_words">Reserved Words</h2> <div class="level2"> <p> When choosing an identifier, there are words that should be avoided.
