Line 3:

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 gonebeen removed, though thesethis areis more commonly called [[unused variables|unused]] or [[unreferenced variable]]s.

The term is taken by analogy with [[oxbow lake]]s which are formed in nature when

a bend in a river becomes so pronounced that the water breaks through

from 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. As in nature, so in code :)

== History ==

This article's author first heard the term from David C. Wood at the University of Kent at Canterbury

in the mid 1980s.

== Examples ==

(from

[http://cvs.savannah.gnu.org/viewcvs/gnash/server/asobj/Global.cpp?rev=1.46&root=gnash&view=markup gnash/server/asobj/Global.cpp 1.46])

<syntaxhighlight lang="Cpp">

<code>

static void

as_global_escape(const fn_call& fn)

{

// List of chars we must convert to escape sequences

const string hexdigitsstrHexDigits = "0123456789ABCDEF";

string inputstrInput = fn.arg(0).to_string();

URL::encode(inputstrInput);

fn.result->set_string(inputstrInput.c_str());

}

</syntaxhighlight>

</code>

In this, "hexdigitsstrHexDigits" is oxbow code (or oxbow data).
