In VBA, an assignment of variables of type Object is a shallow copy, an assignment for all other types (numeric types, String, user defined types, arrays) is a deep copy. So the keyword Set for an assignment signals a shallow copy and the (optional) keyword Let signals a deep copy. There is no built-in method for deep copies of Objects in VBA.
A Java example, when "copying" an object using simple assignment: Object original = new Object (); Object copy = null ; copy = original ; // does not copy object but only its reference The object is not duplicated, the variables 'original' and 'copy' are actually referring to the same object.

Web site owners who do not want search engines to deep link, or want them only to index specific pages can request so using the Robots Exclusion Standard (robots.txt file). People who favor deep linking often feel that content owners who do not provide a robots.txt file are implying by default that they do not object to deep linking either by ...
Copy and paste is a less formal alternative to classical branching, often used when it is foreseen that the branches will diverge more and more over time, as when a new product is being spun off from an existing product. As a way of spinning-off a new product, copy-and-paste programming has some advantages.
Copy-on-write (COW), also called implicit sharing [1] or shadowing, [2] is a resource-management technique [3] used in programming to manage shared data efficiently. Instead of copying data right away when multiple programs use it, the same data is shared between programs until one tries to modify it.
