SPELL(I)                     2/26/74                     SPELL(I)







NAME

     spell - find spelling errors



SYNOPSIS

     spell file ...



DESCRIPTION

     Spell attacks the same problem as typo  (I),  but  from  the

     opposite  direction.  It extracts words from the input files

     and  looks  them  up   in   Webster's   Seventh   Collegiate

     Dictionary; any words which appear neither in the dictionary

     nor in a list of about 2000  words  frequently  occuring  in

     Bell  Laboratories  documents  are listed on the output file

     sp.out.   Words  which  are  reasonable  transformations  of

     dictionary  entries (e.g. a dictionary entry plus s ) are so

     marked; words which could not be found even when transformed

     are marked with asterisks.



     The process takes on the order of 5 to 10 minutes.  There is

     a limit of nine input files.



FILES

     /usr/lib/w2006,  /usr/dict/words,  sp.out;  spjnkq[123]  are

     temporaries.



SEE ALSO

     typo (I)



BUGS



     There should be no limit on the number of input files.



     More suffixes, and perhaps some prefixes, should be added.



     It should be usable as a filter.
