A subroutine (e.g. procedure or subprogram) is a portion of code within a larger program, which performs a specific task and can be relatively independent of the remaining code. The syntax of many programming languages includes support for creating self contained subroutines, and for calling and returning from them. They are in many ways similar to functions, but usually have side-effects outside of the simple "return value" that functions return.
