            INTRODUCTION
            
            
            The Hybrid Btrieve Browser is a TSR (Terminate and Stay
            Resident) program. It will load into memory and then return
            control to DOS until you enter the hot key combination of
            ALT + LEFT SHIFT + R. The Hybrid Btrieve Browser will then
            open the specified Btrieve file and display the fields setup
            in the HBB.DSC description file.
            
            The description file contains all the information needed to
            open and display up to 10 different file views, with each
            view having up to 10 fields displayed at one time. You can
            switch between views, scroll the view screen four ways (up,
            down, left, right), search for a specified key, or paste one
            of the view fields into the keyboard buffer, which can be
            intercepted by the program that the browser was popped up
            over.
            
            The Hybrid Btrieve browser currently takes up about 85K of
            conventional memory.
            
            This program can be used to display name, address and
            telephone information of frequently contacted people (ex.
            customers, patients, vendors). It can be used to add quick
            searching capabilities to existing programs. It can even be
            used to display popup help information.

            SYSTEM REQUIREMENTS
            
            
            To run this software you will need an IBM PC, XT, AT  or
            compatible with a minimum of 512K. DOS version 3.x or higher
            and Btrieve version 4.10 or higher are required. The Hybrid
            Btrieve Browser will only popup over text screens. It will
            work with 43 and 50 line text modes. However, it will not
            popup if you are in graphics mode.
            
            
            
            INSTALLATION
            
            
            Installation of this software is very easy.  Copy all of the
            files on this disk into the drive and directory in which the
            browser will be run. Only three files are actually needed.
            HBB.EXE (the browser program) , HBB.DSC (either the demo
            description file provided on this disk or an HBB.DSC file
            that you created), and a Btrieve file (either the demo data
            file HBB.DAT or a data file that you specify in your HBB.DSC
            file).
            
            
            
            FILES INCLUDED
            
            
            HBB.TXT     - This document file
            HBB.DSC     - Demo description file
            HBB.DAT     - Demo data file
            HBB.EXE     - Hybrid Btrieve Browser program
            DEMO.BAT    - Batch that will load Btrieve and run HBB.EXE
            BTRIEVE.EXE - Btrieve for DOS network version 5.10
            README.1ST  - ASCII file indicating Btrieve was already
                          patched to work with this TSR

            PATCHING BTRIEVE
            
            
            If you elect to use your own copy of Btrieve, instead of the
            one provided on this disk, you will need to patch the file
            using debug. If you don't patch it, the program will freeze
            on the first call Btrieve makes to DOS.
            
            Btrieve version 4.xx and 5.xx checks to make sure that DOS
            is not in a critical state before calling DOS to do a
            Btrieve operation. If the flag is set Btrieve will loop,
            waiting until DOS is not in a critical state before
            continuing. This looping will cause the system to hang. The
            following debug patches to Btrieve will jump past this
            checking and allow the Btrieve operation to be performed.
            
            
            Version 4.xx
            ------------
            
            Copy Btrieve.exe to Btrieve (Don't put an extension on the
                                         destination file.)
            
            debug Btrieve
            
            -r  (check registers, find the value of CX (length of file),
                 for example CX = a61c, then use this address in the
                 next line)
            
            -s 0 a61c b8 00 34  (this will return 2 addresses)
            
            xxxx:QQQQ  (where QQQQ is used to reference address 1)
            xxxx:RRRR  (where RRRR is used to reference address 2)
            
            -u QQQQ  (unassemble to look for first "pop es")
            
            -a QQQQ  (assemble)
            
            xxxx:QQQQ jmp AAAA:BBBB  (where AAAA:BBBB is the address
                                      of the first "pop es")
            
            xxxx:QQQS (just hit enter)
            
            Do the same thing for address RRRR
            
            After changing QQQQ and RRRR
            
            -w  (save back)
            
            -q  (quit)

            THE DESCRIPTION FILE
            
            
            The description file is the heart of the Hybrid Btrieve
            Browser system. It contains all the information needed to
            display up to 10 different views, with 10 fields per view.
            
            The HBB description file is a simple ASCII file. It is
            similar to the description file used by Btrieve to define
            the record length, page and index information for the
            Btrieve file when it is created.
            
            The HBB program only looks at the data contained between
            quotation marks. All other information is used to make the
            description file more readable. Blank lines can be used to
            separate groups like view information and field information.
            Value names like "default view = " can be used to easily
            identify what the value means.
            
            Below are examples of each value needed in a description
            file. An explanation of what it is used for appears on the
            right hand side..
            
            
            default view = "2"               | Use view number 2 when  |
                                             | HBB is started up.      |
            
            # of views = "3"                 | The total number of     |
                                             | views is 3.             |

                                             | of the Btrieve file.    |

                                             | the file was created.   |

            CHANGING THE DEMO DESCRIPTION FILE
            
            
            Before you try creating you own HBB.DSC file, you might want
            to try changing the demo HBB.DSC file.
            
            Below is a listing of the contents of the demo HBB.DSC
            description file, the record layout of the demo HBB.DAT
            Btrieve Data file, and the Btrieve description file that was
            used to create the demo HBB.DAT file. This is included in
            case you want to experiment with changing the indexes in the
            demo description file.
            
            To run the Hybrid Btrieve Browser with the demo data and
            description file you need to run Btrieve with a page size of
            2048 (ex. BTRIEVE /P:2048).
            
            You might want to start off by changing some titles and
            display field lengths. If you change a length, be sure not
            to make it longer than the defined length in the data file.
            
            Next you can remove the "Attention" field from the first
            view. Remember to change the "view # of fields = " from 7 to
            6.
            
            Next, add the Btrieve data file "rep" field to the second
            view. Be sure to increase the "view # of fields = " by 1.
            
            Finally, try adding a new view to the description file. This
            view should contain account, name, contact1, rep, and misc.
            Also, use index #1 (index by name), and make the paste field
            the contact1 field.

            RUNNING THE HYBRID BTRIEVE BROWSER
            
            
            In order to run the Hybrid Btrieve Browser, you must first
            run Btrieve with any switches needed to open the files that
            are defined in the description file. After Btrieve is loaded
            just run HBB.EXE. The program will load into memory and
            display a small window indicating it is loaded and showing
            the hot key combination (ALT + LEFTSHIFT + R) needed to pop
            it up. Then, from DOS or from within a text display program,
            you can use the hot key to pop up HBB.
            
            
            HBB Option Selections
            ---------------------
            
            View   - Type "V" for View and a window will come up showing
                     the different views that you can select. A maximum
                     of five views will display in the window. If there
                     are more than five views you can use the arrow keys
                     to scroll to the desired view. If an error occurs
                     when trying to open a Btrieve file, the last view
                     will be redisplayed.
            
            Search - Type "S" for Search and a window will come up
                     prompting you for a value (index key) for which to
                     search. Before the search begins, the value you
                     type in will be converted into the proper format
                     (Btrieve Extended Key Type). The index key type is
                     define in the description file. A "greater than"
                     search will be performed. The first record found
                     with a key greater than or equal to the search
                     field will be displayed as the highlighted browse
                     record. If End Of File is encountered, then the
                     last record in the file will be highlighted.
            
            Paste  - Type "P" or ENTER to paste the predefined field
                     into the keyboard buffer. A carriage return is
                     appended to the field to reduce the number of
                     keystrokes needed for data entry. The paste field
                     number is defined in the description file.
            
            Unload - Type "U" to unload the Hybrid Btrieve Browser from
                     memory.
            
            About  - Type "A" to display a window describing version
                     and copyright information.
            
            Help   - Type "H" to display a window containing the
                     navigation and selection keys that can be used in
                     the HBB main display. You can scroll this screen
                     using the arrow or page keys.

            COMMAND LINE SWITCHES
            
            
            The Hybrid Btrieve Browser has one command line switch:
            
            HBB /U
            
            This will unload the HBB.EXE file without having to pop it
            up and type "U" to unload.

            FUTURE VERSIONS
            
            
            While writing this documentation I have accumulated some
            thoughts on what features the next version of this product
            might include. If you have a preference for any of these
            features, or have some other suggestions please drop me a
            note on compuserve. My number is 75140,3705.
            
            The features included in the next version will depend
            greatly on the response I receive to this first version. I
            would appreciate any comments or suggestions that you might
            have regarding this product.
            
            
            Below is a list of enhancements being considered:
            
            Store the view information in a Btrieve file instead of an
            ASCII file, thus reducing memory requirements. Introduce a
            new program to maintain this Btrieve view file. This would
            include conversion of existing ASCII view files, Adding,
            Changing, Deleting and Querying view information.
            
            Swap HBB.EXE to extended/expanded memory or to disk when not
            in use.
            
            Expand on-line help to display an index of help topics
            instead of just the one help screen.
            
            Expand the displayable field types to include integers,
            longs, floats, and perhaps user defined formats/masks for
            strings and numbers.
            
            Provide command line switches for default view and a user
            specified description file name. This would allow you to
            have different description files for different users,
            without putting the files in different directories or paths.
            
            Display more information about the current view, for example
            view name, data file name, path, key number, key field name,
            paste field name, free memory, free disk space, number of
            records in the current view file, and Btrieve version.
            
            Allow a view to be used for text display purposes. This
            would mean you would not see a highlight bar. You would not
            need to paste anything or search the key field. This would
            make HBB.EXE better for displaying help or reference
            information.
            
            Provide the ability to search all the display fields for a
            string value, not just the index field. If a record is found
            with the string value, then bring it up on the screen as the




                                    Page 16








            highlighted record. Also include the ability to continue or
            abort the search.
            
            Save the browse screen information so the next time the view
            is displayed it will appear the same as the last time it was
            viewed.
            
            User specified hot keys.

            ERROR MESSAGES
            
            
            Most error messages that will be generated by the Hybrid
            Btrieve Browser will result from an invalid description file
            or a Btrieve error. If you get an error reading the
            description file you should check your HBB.DSC file very
            carefully for mistakes.
            
            
            Some Common Description File Errors
            -----------------------------------
            
            The value you enter for the # of views is greater than the
            actual number of views defined.
            
            The value you enter for the view # of fields is greater than
            the actual number of fields defined.
            
            One of the values is not within the allowed range, For
            example, the VIEW # OF COLUMNS minimum is 26 and maximum is
            70. If you enter 20 or 76 for this value you will get an
            error. You can find the value ranges in the section THE
            DESCRIPTION FILE.
            
            
            Some Common Btrieve Errors
            --------------------------
            
            Btrieve error number 20 means Btrieve is not loaded. Load
            Btrieve then run HBB.EXE again.
            
            Btrieve error number 12 means the file you defined in the
            description file can not be opened. This could be the file
            does not exist or if you are on a network, you may have
            logged into a user area that does not have access to that
            file.
            
            For most other Btrieve error codes returned by HBB you
            should refer to your Btrieve manual.
            
            When in doubt you can unload Btrieve, then load it again
            (make sure you use the correct /M and /P command line
            switches) and then load HBB.EXE again to see if the error
            occurs again.
