This is well-suited for machines with [[tape drive]]s. Use has declined due to large [[random access memory\|random access memories]], and many applications of merge algorithms have faster alternatives when a random-access memory is available.{{Fact\|date=May 2009}} The general merge algorithm has a set<!--non-technical use, don't link--> of [[pointer (computer programming)\|pointer]]s p<sub>0..n</sub> that point to positions in a set of lists L<sub>0..n</sub>. Initially they point to the first item in each list. The algorithm is as follows:
