over 180,000 words to my manuscript and I want to know how many unique words to the 'script. Word Counter stalls. Months ago I attempted to write my own script to do the task; one script was fast but very innaccurate, the other script I would've had to left the computer and script running continuously for weeks, and this I could not do. I do know the problems involved in writing the script to give the results I want though. I used Word Counter years ago when my 'script was less than a hundred thousand words, and it did give a number which I rounded off to 9700 unique words. This was cool though I would like an update, and like I mentioned before, I do understand the complexities involved in deriving accurate and unique word counts from large worded tomes. Other word processing applications sudh as Nexus that claim to have an unique word count function cannot handle large files either. The unique word count problem should be posed inside a computer science textbook as a challenge. One will certainly learn alot about programming and code and algorithms attempting to tackle the unique word problem ... giving accurate results fromlarge text files that is.
