Constructor Function: string()

This section describes 'string' constructor function string().

New "string" data object can be created with the "string" constructor function, string(), which has the following syntax:

string(a = "")

   a - A "string" data object. Default is "".

   Returns a new "string" data object representing 
   the same value as "a".

Examples of how to use "string" constructor function:

string(); # create a new data object representing "" 

x = string(); # assign a new data object representing "" to x

# assign a new data object to y
y = string("Hello world!"); 

Design options:

1. Let the constructor return "" if no parameter provided.

2. Make the parameter as required for the constructor.
