string object
This method returns the length of the string.
uint get_size()
Parameters:
None.
Return value:
The length of the string, or 0 if the string is empty or if an error occurs.
Remarks:
Please note that the value returned is the length of the string rather than the index of the last character in the string. Therefore when using the get_size method as a basis for a loop it is important that you check that any counting variable accessing individual characters in the string stops when the counter reaches the length mark, not beyond it. This is because the index is 0 based. In other words, with a string containing 3 entries you may access elements 0, 1 and 2.
Example:

    // Declare a string and display its characters.

    void main()
    {
    string[] hello;
    hello="Hello";
    alert("String", "The string "+hello+" contains " + hello.length() + " characters.");
    for(int counter=0; counter<hello.get_size(); counter++)
    {
    alert("String", "Character "+counter+" is "+hello[counter]+".");
    }
    }
