At Denison University we have updated our program which checks spelling. The changes include an option to rigorously check the spelling of a word and an option to interactively correct misspelled words. The updated speller was designed with a focus on maintaining the program's efficiency. As a result, there are a large number of components, many requiring special attention. The word spelling checker, all the search algorithms, and some of the support routines were written in VAX-11 MACRO. The other routines and programs were written in VAX-11 BASIC. The program makes use of features available in VMS version 3 and the EDT editor. Therefore, this system will run only on Digital's VAX-11 machines running under VMS version 3.0 or higher. This program was originally released on the Fall, 1981 DECUS tape. Any new changes in the documentation file AAAREADME.DOC will be highlighted by an asterisk.
