call-by-reference         
<programming> An argument passing convention where the address of an argument variable is passed to a function or procedure, as opposed to passing the value of the argument expression. Execution of the function or procedure may have side-effects on the actual argument as seen by the caller. The C language's "&" (address of) and "*" (dereference) operators allow the programmer to code explicit call-by-reference. Other languages provide special syntax to declare reference arguments (e.g. ALGOL 60). See also call-by-name, call-by-value, call-by-value-result. (2006-05-27)

Reference type; Reference types; Value type; By-value type; By-reference type
In computer programming, data types can be divided into two categories: value types and reference types. A value of value type is the actual value.
Reference work         
  • The ''[[Brockhaus Enzyklopädie]]'', the best-known traditional reference book in German-speaking countries
  • ''[[Encyclopædia Britannica]]'', 15th edition: volumes of the Propedia (green), Micropedia (red), Macropedia (black), and 2-volume Index (blue)
  • The ''[[Lexikon des Mittelalters]]'', a specialised German encyclopedia
PUBLICATION TO WHICH ONE CAN REFER FOR CONFIRMED FACTS
Reference works; Reference book; Reference textbooks; Reference texts; Reference books; Refernce textbooks; Reference document
A reference work is a work, such as a book or periodical (or their electronic equivalents), to which one can refer for information. The information is intended to be found quickly when needed.

Evaluation strategy

In a programming language, an evaluation strategy is a set of rules for evaluating expressions. The term is often used to refer to the more specific notion of a parameter-passing strategy that defines the kind of value that is passed to the function for each parameter (the binding strategy) and whether to evaluate the parameters of a function call, and if so in what order (the evaluation order). The notion of reduction strategy is distinct, although some authors conflate the two terms and the definition of each term is not widely agreed upon.

To illustrate, executing a function call f(a,b) may first evaluate the arguments a and b, store the results in references or memory locations ref_a and ref_b, then evaluate the function's body with those references passed in. This gives the function the ability to look up the argument values, to modify them via assignment as if they were local variables, and to return values via the references. This is the call-by-reference evaluation strategy.

Evaluation strategy is part of the semantics of the programming language definition. Some languages, such as PureScript, have variants with different evaluation strategies. Some declarative languages, such as Datalog, support multiple evaluation strategies. Some languages define a calling convention.
