Arrays

WMLScript does not support arrays as such. However, the standard String library supports
functions by which array-like behavior can be implemented using strings. A string can contain
elements separated by a specified separator. For this purpose, the String library contains functions
which allow you to create and manage string arrays. The following is an example of an array
operator:
function dummy() {
var str = “Mary had a little lamb”;

var word = String.elementAt(str,4,””);
};

Pragmas
WMLScript supports the use of pragmas that specify compilation unit level information. Pragmas
are specified at the beginning of the compilation unit before any function declaration.

Notes Note that all pragmas start with the keyword use and are followed by pragma-
specific attributes.
