'''Control flow''' refers to the means for controlling the order in which sections of a [[program]] are executed.

The underlying [[Central Processing Unit|CPU]]'s [[instruction set]] has a number of '''transfer of control''' primitives: jump/branch, both un-conditional as well as [[conditional branch]]es; and [[subroutine]] calls.

[[Programming language]]s often add additional mechanisms, particularly '''block structures''', in which a group of instructions are treated as a unit for various control mechanisms (e.g. loop control, if-then-else constructs, etc).

Blocks are also often used to control the [[scope]] over which variables (particularly [[local variable]]s) are accessible.

[[Interrupt]]s and [[exception]]s also divert the flow of control in a computer, but at times which are not always predictable.
