By engaging approximate string matching in our applications, we have this opportunity to write more intelligent and more user friendly applications. In this post, you will find the Delphi implementation of Damerau-Levenshtein distance algorithm to use for writing another Delphi function for fuzzy matching of two strings.

Sometimes we need to locate and replace more than one substring in a string, and Delphi does not have a function for this purpose. In this post, I implement and discuss such a function.
