          FUNCky Demo Program Copyright dLESKO ASSOCIATES 1988. All Rights
          Reserved. No part of this program may be distributed for any
          purpose other than to demonstrate the capabilities of the FUNCky
          Library for Clipper

          View is a sample program written using functions from the FUNCky
          library for Clipper that demonstrates usage of the mouse
          functions, programming for multiple video modes, font loading and
          in general the basic principles when creating dropdown tear off
          menus similar to the Macintosh interface. With view you can view
          text files in moveable and resizeable windows. View supports
          almost every video mode you can throw at it (except graphics
          modes) with no special programming. If you have an EGA or VGA and
          your adaptor supports 43, 50 or 60 line mode, View will love it.
          If you can go up to 132 columns, you can also see how Clipper can
          now work in those modes as well.

          To start View, simply type View and optionally the drive letter
          of the drive you wish to view text files on. As in the sequence:

               View C: <return>

          Once View has started, a status line on the bottom of the screen
          displays the currently selected drive, path and filename. To view
          a file, select the directory you want to view, then select the
          file, then select view from the menu and a window will open
          displaying the contents of the text file. You can bring up
          multiple views of the same text file by pressing F1 after you
          display the first view window. The maximum
          number of windows you can open is 4. Use the mouse to move the
          windows to make room for the new window before you open a new
          window since only the top window is active.

          The various aspects of the mouse functions can be demonstrated as
          well. If you have a mouse, you can click on any option to pull
          down the sub menu. To select a sub menu item, just click on that
          item and it is selected. The idea of tear off drop menus is
          accomplished by placing the mouse cursor in the middle of the sub
          menu and pressing the right mouse button. While holding it down
          you can drag the sub menu anywhere on the screen you like. You
          can also re-size the drop down menu by placing the mouse cursor
          on the right border of the box and while holding down the right
          mouse button, drag the box's border to the right or left. To
          display more lines of the drop down menu, place the mouse cursor
          on the bottom edge of the box border and while holding down the
          right mouse button, pull the box border up and down. Another
          type of moveable window is available. In the mode window you
          can specify Macintosh like or normal. Macintosh windows move around
          a little faster since only the frame of the window is drawn as
          you move it. The entire window is repainted only when you release
          a key or mouse button.

          You can also use the mouse to emulate all the keyboard like
          control keys. To scroll up the menu, click the left mouse button
          while the mouse cursor is on the up arrow in the control panel.
          To scroll down, click the left button while the mouse cursor is
          on the down arrow. To page up and page down, click the right
          mouse button on the up or down arrow. You can also pan the inner
          contents of the menu if the contents exceed the width of the
          menu. Just click the left or right button on the left and right
          arrows in the control panel of the menu. The file view window
          also emulates these same procedures, except that the panning
          arrows move the contents of the text file in 8 column increments.

          If you don't have a mouse you can still emulate all the above
          outlined options using the keyboard. Press the scroll lock key
          and then use the arrow keys on the numeric keypad to move the
          drop down menu, or the file view window to the position you like
          on the screen. When it is in place, release the scroll lock key.
          To expand the drop down menus, use the left shift key and the
          arrow keys on the numeric keypad to expand or grow the dropdown.
          the left and right arrow keys expand the box right and left while
          the up and down arrow keys pull up or down the bottom of the
          dropdown. To select menu items, you can scroll the highlight to
          any item you want and press return to select it.

          That's about all there is to view. If you have an EGA or VGA
          monitor, you can check out the various screen modes and fonts in
          the MODE option on the main menu. Study the VIEW.PRG file to see
          how it was done. Note that you cannot compile the source code if
          you do not have the FUNCky Library for Clipper. The following
          text outlines some of the capabilites of the library. A listing
          of the table of contents list the major functions in the library.
          Give it a looksee, if you like it I guess I'll be speaking to you
          soon.....

          What is FUNCky you ask? - well, I think it's the neatest library
          to ever come out for Clipper.....

          With FUNCky you have the largest array of functions ever
          assembled in one place. You get top quality documentation on over
          400 functions for Clipper. There are also around 30 or so re-
          written Clipper functions. They have been written in tighter
          faster code. With greater speed so you get increased options.
          Like with FILE IO. The low level file funcitons in Clipper have
          been completely re-written so that you can now do things like
          store your menu options in text files that you can edit inside
          the appplication using memoedit(). You can create help systems
          that display text files in windows, use the fantastic flocate()
          function to locate text strings in files, then use the speedy
          freadline() to read the lines of text into a string. You could
          use afileread() to load lines of text from a file into arrays.
          All the low level file functions of course interact directly to
          with Clipper's own ferror() function.

          You also get mouse support, not little dweeby functions to read a
          mouse button or display a mouse cursor, but real mouse support.
          use mx_choice() to emulate achoice() with scroll bars, a control
          panel, resizing, dynamically expanding windows, grab the window
          and move it. Display DBF files like dbedit() in the same type of
          dynamic windows. Use the mouse to select records or scroll the
          database. Grab the window and move it so you can pop up several
          DBF scroll windows at once!, use mx_view() to view text files in
          the same type of moveable-resizeable windows. Create popup,
          dropdown, tear off, moveable, resizeable menus, etc. etc. etc.
          All in all around 70 mouse functions to do almost anything you
          want,

          You also get extensive video support. You can use as many video
          pages as your adaptor supports, create virtual screens and
          windows in memory, display menus on the monochrome screen and
          color screen at the same time (if you have two monitors), write
          programs in 43 and 50 line mode on your EGA or VGA adaptor with
          full support of gets / menu to / savescreen() etc... Get 64
          colors on EGA and VGA monitors, use the print() function to write
          strings to the screen 50% faster than @ ... say. Use all the
          regular Clipper functions like @ ... box, @ ... say etc. inside
          virtual screen buffers that are not displayed until you want
          them. This negates the need for complex windowing functions.

          You can also execute functions during wait states like menu to or
          READS using the great timeout() function!. Intercept and remap
          keystrokes with the cool onkey() function!. Create neato sound
          effects with sound()!. Load different FONTS into your EGA and VGA
          adaptor!, display 2 fonts at the same time!, get 16 background
          colors where you used to have only 8!, get access to the F11 and
          F12 keys with built in extended keyboard support!, Whew!... Have
          to catch my breath...Plus you get all the usual functions you
          expect from a library by dLESKO ASSOCIATES.

          Now, the price. It's three tiered. First, list is $195 direct
          from dLESKO ASSOCIATES at 201.435.8401. Next is the user group

          user group, now is the time to join! save money on your membership
          dues, and spread the word. Have you user group leader call us
          for more information on the user group FUNCky promotion.
          You can call during the day if you want more information. By the
