    print $name . " as integer: " . $iValue . "\r\n";

}

# Note: The StringAt method returns the value as a string regardless of the type.
# If the value is a JSON array (such as for ["home", "green"]), then the JSON encoding
# of the entire array is returned.

# The IntAt method returns the value as an integer.  If the value does not convert to 
# an integer, then 0 is returned
