Oxbow code

rdf:langString Oxbow code

rdf:langString In computer programming, oxbow code refers to fragments of program code that were once needed but which are now never used. Such code is typically formed when a program is modified, either when an item is superseded with a newer version but the old version is not removed, or when an item is removed or replaced, but the item's supporting code is not removed. Such code is normally removed unless sufficiently amusing or educational. Similarly, variables and data structures can be left around after the last code that used them has been removed, though this is more commonly called or unreferenced variables. The term is taken by analogy with oxbow lakes which are formed in nature whena bend in a river becomes so pronounced that the water breaks throughfrom before the bend to after it, making the river straight again.When the sides of the new course silt up, a curved lake is left,disconnected from the main stream.
