1  GENERAL COMMENTS

     At Denison  University  we  have  expanded  our  English  grammar
     system.   The  changes  to  the  English  text  criticism program
     include the addition of several style  checks,  screen  features,
     and  a  instructive  help  library.  The spelling error detection
     program includes an option to rigorously check  the  spelling  of
     words  and  an  option to correct misspelled words interactively.
     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 4 and the callable
     EDT editor.  Therefore, this system will run  only  on  Digital's
     VAX-11 machines running under version 4.0 or later.  This program
     was originally released on the Fall, 1981 DECUS tape.

          Many of the fundamental algorithms and data  files  in  this
     system  were  based on those of a journalism package developed at
     the University of  Michigan.   The  frequency  ordering  for  the
     common English words were extracted from the University of Iowa's
     Monograph in Education titled "A Basic Writing Vocabulary; 10,000
     Words  Most Commonly Used in Writing" by Ernest Horn, PhD.  (This
     book was found under the card catalog subject of "vocabulary" and
     has  a  Library  of  Congress  catalog  number LB 5.I62.) Further
     information on spelling can be obtained from  "Computer  Programs
     for  Detecting  and  Correcting  Spelling  Errors"  by  James  L.
     Peterson in the Communications of the ACM,  December  1980,  page
     676.

          Because this system contains  proprietory  dictionaries,  we
     cannot distribute source code at this time.

          NOTE:   This  is  a  RERELEASE  of   the   GRAMMAR   package
     distributed  on  the  Fall  1985  DECUS  tape. (Librarian's note:
     I believe they mean Fall 1983.)  This release has corrected  most
     of the errors found in the previous versions and upgraded compat-
     ibility with VAX/VMS 4.0 and above.
