The KWAC Index Generation Program was implemented at the State University of New York at Buffalo. It consists of only 252 statements for the COBOL Compiler Edition V310222 on the CDC6400 computer under the KRONOS operating system in the batch mode. The KWAC program is essentially a KWIC index generator designed for a special purpose for use in a particular course, though it has sufficient flexibility to be used in other, similar contexts. The program takes free form natural language input, and generates an index in alphabetical order of each significant word appearing in the input alongside which appears the bibliographical description of the document in which the word was located. Output options permit free form title page, introduction, and epilog. Page headers and footers are permitted, and index page numbers are assigned and printed automatically. Determination of significant words is made in two ways: 1) a word is determined to be significant by default, if it does not appear in a user-input stop list and provided it begins with an alphabetic character and it is more than one character long; and 2) an otherwise significant word may be eliminated from the indexing by a simple procedure at the time of input.
