This file is KEYWORDS.TXT.  It lists all the statements,
        functions, and metastatements from TurboBasic and PowerBasic.
        Very useful when converting source code from one to the
        other.  Of course, PowerBasic is almost completely
        backwards compatible with TurboBasic - you should rarely
        have any problems.  If you really want to use PowerBasic
        source code, it is much better to contact Spectra Publishing
        about upgrading - they seem eager for TurboBasic users to
        move up to PowerBasic.  There are many other reasons, some
        of which become apparent from browsing the following listing.
