Definition
A subroutine (also called a subprogram) is “a routine that can be part of another routine; analogous to a sentence within a paragraph of narrative text.”[1]
Overview
As the name suggests, a subprogram behaves in much the same way as a complete computer program that is used as a step in a larger program. A subroutine is often coded so that it can be executed (called) several times and/or from several places during a single execution of the program, including from other subroutines, and branch back (return) to the point after the call once its task is done.
