FILBUF.LIB
                                 by Jim Kyle

  This library includes two language-independent functions that will determine
the number of FILES and the number of BUFFERS presently configured in any
system running MS-DOS versions 2.0 through 5.0.  These functions do NOT work
with DR-DOS or in the DOS box of OS/2.

  Also included are two sample files, for any compilable BASIC and for any
version of C that recognizes the "pascal" and "far" keywords, which
demonstrate the use of these functions.

  For details of the way in which these functions operate, see Chapter 4 of
the book "Undocumented DOS", ISBN 0-201-57064-5, published by Addison-Wesley
Publishing Co., Inc., and available anywhere technical computer books are
sold.  Kyle is the author of that chapter.  These functions are based on the
programs published in the book, but have been converted to assembly language
and all dependency on any language-specific compiler libraries has been
removed.  Consequently, they operate equally well when called from C, BASIC,
and Pascal.

  If you find this library useful and would like to obtain commented source
code for both functions, in 8086 assembly language, you can register your copy
for $20 US.  You will receive a diskette containing commented source code and
the latest version of the library, together with a pair of executable files
that make the FILES and BUFFERS value accessible to BATch programs, and your
name will be added to the list of registered users who will receive
notification of any additional utilities developed.
