Ī function is often coded so that it can be started several times and from several places during one execution of the program, including from other functions, and then branch back ( return) to the next instruction after the call, once the function's task is done. The generic umbrella term callable unit is sometimes used. Technically, these terms all have different definitions, and the nomenclature varies from language to language. In different programming languages, a function may be called a routine, subprogram, subroutine, or procedure in object-oriented programming (OOP), it may be called a method. This unit can then be used in programs wherever that particular task should be performed.įunctions may be defined within programs, or separately in libraries that can be used by many programs. In computer programming, a function or subroutine is a sequence of program instructions that performs a specific task, packaged as a unit.
