                     Printer Control Function Library

                               $99 Complete


       What?  You don't have a library dedicated to coding reports,
       controlling the printer, handling errors, dealing with the end-
       user, and managing printer control codes?

       You are wasting too much time.
       -----------------------------------------------------------------

       Imagine being able to send reports to the printer, a text file,
       or to the screen... under end-user control, at RUN-TIME, without
       changing a SINGLE BYTE of source code.  If you use our highly
       efficient library functions it will happen automatically.

       Imagine never having to type @ PROW(), PCOL() SAY ever again.  We
       have replacements for these and other commands.  Once you see our
       method you will never go back to the "old" way.

       Imagine run-time printer errors that are handled transparently by
       the library.  Cancel reports, retry and so on.  You can regain
       control of your application, even if the end-user turns off the
       printer in the middle of the report.

       If that were all we provided, the Printer Control Function
       Library would be a pretty good deal.  But that's not all we
       provide.  Also included are manual sections on how to layout
       better looking reports, how to implement various features of the
       library in your existing applications, and much, much more.

       The manual IS NOT just an alphabetic listing of the functions and
       a few pathetic comments about how they are used.  We have
       developed a comprehensive product that addresses the ENTIRE
       PRINTING PROCESS, from laying out the report, coding it,
       presenting user options, sending control codes, handling run-time
       errors.

                   User Interface and Screen Control Library

                                $99 Complete


       Ok, so you might admit that you aren't handling the printer as
       well as you could be, but you definitely have a nice set of user
       interface routines...

       Ours are better.

       What arrogance.  Audacity.  How cheeky.  (Just love that on-line
       thesaurus).

       -----------------------------------------------------------------

       This is the only library you can buy that has been designed from
       the ground up to be an integrated user interface system.  After
       years of doing it mostly right and sometimes totally wrong, we
       started from scratch and have developed a system that drives
       Clipper like it was meant to be.

       Pop-up, pull-down, light-bar, multiple-choice-- it's all in here.
       We provide bullet proof routines for all the common prompting
       situations:  String, date, numeric, logical, multiple choice and
       so on.  Then we add a top-notch screen color/attribute handler,
       several highly efficient replacements for "@ ROW(), COL() SAY", a
       unique context-sensitive "repeat the previous response" function,
       an on-screen ruler that will make complex layouts much easier,
       (get a free copy of the ruler by downloading RULER.ARC in
       NanForum), and several other innovations.

       Most of the functions calculate row/column coordinates
       FROM CONTEXT.  You don't have to pass them as parameters.

       As with the Printer Control Function Library, the manual is the
       very best you will ever see associated with a Clipper add-on
       product, especially at our low price.  It's much more than just a
       quick run-down of the library functions.  You get details on the
       theory and practice of a good user interface.  Real-life horror
       stories of the wrong way to do things.

       -----------------------------------------------------------------

       Don't forget the guarantee.  We just told you our library does
       things BETTER than whatever you are currently doing.  Take up
       the challenge.  Buy it.  You can't loose.  Either you get the
       best interface lib on the market, or you send it back for a
       refund, happier than ever with "your way".

                      bugArry - The Array Debugger


       Have you ever popped up the Clipper DEBUG.OBJ debugger, hoping
       to shed some light on an array problem?  Depressing, isn't it?
       DEBUG doesn't like arrays very much.  You can't see more than
       one element at a time, and only after typing out the full
       array name and subscript over and over again.

       bugArry is designed to fill the gap.

       -----------------------------------------------------------------

       With bugArry you can view the contents of any array in a
       scrolling window, with each data type (character, date, logical,
       integer, real and undefined) formatted individually for clarity.
       bugArry also displays a condensed map of any array so you can
       quickly spot unusual elements or patterns.  bugArry will print
       (to a printer or a disk file) the contents of any array for
       documentation and analysis.  And finally, bugArry has a build-in
       configuration editor so you can customize it to better fit
       your needs.  All four functions (view, map, print and setup)
       can be accessed through a unique "hot-key gateway" from any
       wait-state inside your application.

       The bugArry functions can be called from inside the Clipper
       DEBUG.OBJ debugger, directly from inside your application
       through a function call, or indirectly through the use of the
       hot-key gateway.

       The bugArry functions are provided in two "models".  The large
       models can be operated in a prompted or interactive mode and
       have additional on-screen comments.  Smaller models are
       provided to conserve on precious memory by cutting out non-
       essential features.

       A test application is provided for experimenting with bugArry
       in a controlled environment.

       Documentation is very complete and contains a general purpose
       tutorial on arrays.

                   CLIPtrieve - The Clipper/Btrieve Collection

                                $99 Complete


       CLIPtrieve allows Clipper programmers to access the Btrieve
       Record Manager, which is bundled with Novell NetWare. Many major
       commercial applications are based on the Btrieve Record Manager,
       and CLIPtrieve allows Clipper programmers to access and
       manipulate that data.


       CLIPtrieve allows you to:

          o  Convert Btrieve data to DBF-format.
          o  Convert DBF-format data to Btrieve.
          o  Print reports directly from Btrieve without conversion.

          o  Take advantage of advanced Btrieve features like
             transactions, complex index keys, immense file sizes split
             across drive volumes, data integrity, and many more.


       CLIPtrieve comes with a Btrieve interface function-- BTRIEVE()
       --which is called like any other Clipper user-defined function, a
       set of utility functions for converting Btrieve floating-point
       numbers to Clipper numerics, and a complete library of functions
       that allow programmers to use more familiar syntax when making
       Btrieve function calls.  For example-- B_USE(), B_SEEK(),
       B_SKIP() and dozens more.


       And best of all, 100% of the Clipper source code for the function
       library is included at no additional charge!  A comprehensive
       manual describes how the BTRIEVE() interface function works and
       how to link the product into your applications.


       FoxPro and FoxBase programmers... Alto has Btrieve interfaces
       for your dialects as well!  Call for details.

                   MultiMem - The Memory File Manager



       MultiMem slices, dices and blends Clipper memory files
       (.MEM), allowing you to perform a variety of useful
       packaging functions:

       o   Save multiple memvar skeletons or individual
           variable names to a SINGLE file.
           For example,

                SAVE ALL LIKE PRN*, CLR*, SYS* TO CONFIG.APP

       o   Encrypt and decrypt the contents of MEM files
           (or any other block of characters, for that matter)
           for better security with passwords and configuration
           information.

       o   Attach a MEM file to the end of the application's
           EXE file, allowing you to save and restore
           configuration and other information right along
           with the program that needs them-- no more MEM
           file clutter!

       o   View and document the contents of memory files
           via a handy DISPMEM utility, called from DOS.
           List memvars and their types, lengths and
           values to the screen, printer or a text file.
           Works with DOS wild-cards, for example,

                DISPMEM *.MEM > MEMVAR.TXT
