Callable unit

"A function, method, operation, subroutine, procedure, or analogous structural unit that appears within a structural unit of software or analogous logical design, (typically containing several callable units) that are tightly coupled.

"Discussion: Modular design requires that inter-module coupling be loose and occur over defined interfaces. A module should contain all elements needed to compile or interpret successfully and have limited access to data in other modules. A module should be substitutable with another module whose interfaces match the original module. In software, a module typically corresponds to a single source code file or a source code / header file pair. In object-oriented languages, this typically corresponds to a single class of object."
