continuation ==>

continuation passing style

<programming> (CPS) A style of programming in which every user function f takes an extra argument c known as a continuation. Whenever f would normally return a result r to its caller, it instead returns the result of applying the continuation to r. The continuation thus represents the whole of the rest of the computation. Some examples:

 normal (direct style)    -->	continuation passing

 square x = x * x		square x k = k (x*x)

 g (square 23)			square 23 g

 (square 3) + 1			square 3 ( \ s . s+1 )
