PBA Documentation
You can read about how to find the documentation here:

Here are the specifics:
The PBA file is a self-extracting executable archive. After you have downloaded it, find it on your computer and run it (doubleclick it) to extract it and install Professional Blackjack Analyzer. The installation program will put the PDF manual in a subdirectory called "\DOC".
Let me know if you need any help with finding the documentation by emailing me at chris@bj21.com.
