Converts a value to a string.
StrValue := String(Value)
Type: String
This function returns the result of converting Value to a string, or Value itself if it is a string.
If Value is a number, the default decimal formatting is used.
If Value is an object, the return value is the result of calling Value.ToString(). If the object has no such method, a MethodError is thrown. This method is not implemented by default, so must be defined by the script.
