=={{header|REXX}}==
The method used to find a word (that is contained in a specified
dictionary) closest to a specified string of letters is:
Perform any of (three methods of actions):
::* ''delete'' any letter
::* ''insert'' any letter
:::* (any letter is inserted at any location)
:::* (this includes prefixing any letter)
:::* (this includes suffixing any letter)
::* ''substitute'' any letter at any location
<small>(Only lowercase letters were used for the [above] three methods).</small>
Perform any of the above along with any combination of any method.
This will, in effect, delete/insert/substitute any two letters:
::* ''delete'' + ''delete''
::* ''delete'' + ''insert''
::* ''delete'' + ''substitute''
::* ''insert'' + ''delete''
::* ''insert'' + ''insert''
::* ''insert'' + ''substitute''
::* ''substitute'' + ''delete''
::* ''substitute'' + ''insert''
::* ''substitute'' + ''substitute''
No attempt was made to change (by any method) three letters or more.
