The spedis function computes a distance between two strings. Here is an example :

SAS

options nodate pageno=1 linesize=64;
data words;
   input Operation $ Query $ Keyword $;
   Distance = spedis(query,keyword);
   Cost = distance * length(query);
   datalines;
match       fuzzy        fuzzy
singlet     fuzy         fuzzy
doublet     fuuzzy       fuzzy
swap        fzuzy        fuzzy
truncate    fuzz         fuzzy
append      fuzzys       fuzzy
delete      fzzy         fuzzy
insert      fluzzy       fuzzy
