- LEX is a program which performs a number of useful functions on a text
- file. It outputs word count, long word count, sentence count, and performs 3
- readability algorithms on the document. The three algorithms, and their
- meaning, are:
- The Gunning-Fog index: the number equals the approximate level of
- schooling (in years) needed to understand the document.
- The Kincaid index is similar to the Gunning-Fog index in its
- interpretation.
- The Flesch index and Flesch Grade Level indicators: The Flesch index
- is inversely proportional to the difficulty of the document; the lower
- the scale, the harder the document. It is based on a 1-100 scale. The Flesch
- grade level indicator is again analogous to the other two.
- The usefulness of three different indices is to compare their agreement.
- The closer their agreement, the more reliable the measure (they all use
- different algorithms, but usually come out pretty close).
-
- LEX MUST be used from CLI.
-
- LEX can be invoked with the following syntax:
-
- LEX file { file2 file3 ...}
-
- That is, LEX can be used to analyze any number of files in a single
- invocation up to the limits imposed by AmigaDos.
