call-by-value         
(CBV) An evaluation strategy where arguments are evaluated before the function or procedure is entered. Only the values of the arguments are passed and changes to the arguments within the called procedure have no effect on the actual arguments as seen by the caller. See {applicative order reduction}, call-by-value-result, strict evaluation, call-by-name, lazy evaluation.
Call-by-push-value         
Call by push value
In programming language theory, the call-by-push-value (CBPV) paradigm, inspired by monads, allows writing semantics for lambda-calculus without writing two variants to deal with the difference between call-by-name and call-by-value. To do so, CBPV introduces a term language that distinguishes computations and values, according to the slogan a value is, a computation does; this term language has a single evaluation order.
call-by-value-result         
An argument passing convention where the actual argument is a variable V whose value is copied to a local variable L inside the called function or procedure. If the procedure modifies L, these changes will not affect V, which may also be in scope inside the procedure, until the procedure returns when the final value of L is copied to V. Under call-by-reference changes to L would affect V immediately. Used, for example, by BBC BASIC V on the Acorn Archimedes.

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.
