Index prepares an ordered list of "words" used in a file and
outputs each "word" together with the frequency of its usage.
Usage: index <filename>.
DSI32 usage: load index -a <filename>.
This program is useful in writing to check on vocabulary usage. For
instance, the first line of output reports the total number of unique
"words" used. A document of say 10,000 words with a vocabulary of 500
obviously is very repetitious. Similarly a document of 10,000 words
with 4000 or 5000 words is probably using an esoteric vocabulary (or is
typed by a poor typist).
