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.
