    KEYWRD, Word and Phrase Recognition Logic Generator
    ------  ---- --- ------ ----------- ----- ---------

Abstract:  The KEYWRD program produces a sequence  of  tests
which  can  identify  the leading word or the leading phrase
formed of a fixed sequence  of  words  in  a  line  of  text
without  ever  having  to test a character which has already
been identified.  Such a leading word  or  phrase  does  not
need  to include any characters to the right of the first of
the characters which uniquely identify the word  or  phrase.
The word or each of the words in a phrase can be abbreviated
by truncation, leaving at least the left character  in  each
word  of a phrase if additional words or their abbreviations
appear to the right.  Spaces are allowed between  the  words
in  a  phrase,  but  are not required.  A single sequence of
tests is used to recognize the initial portions of words and
phrases which start with a common series of characters, then
the unique portion of each word or phrase is identified by a
separate  sequence  of  tests.   After the unique portion of
each word or phrase has  been  identified  by  the  separate
sequence  of  tests,  then  a  single  sequence  of tests is
similarly used to recognize the final portions of words  and
phrases which end with a common series of characters.
