- ABOUT HLINK.EXE
-
- HLINK.EXE is a program from the kit, PIECES, by Another
- Company. With PIECES, you can create just about anything for
- IBM-compatible computing. No programming skill is necessary.
- See end of this file for more information about PIECES.
-
- What It Does
-
- Hlink delivers interactive user interface to your
- presentations of a type called "Hyperlinking". With Hlink,
- you can display any onscreen image, and the end user is given
- an arrow which can be moved with the mouse, arrow or number
- keys. The user can point to something on your image, click
- the left mouse button or press [Enter] and be taken to
- another part of your presentation. Accompanying HLINK.EXE in
- the PIECES kit of programs is MAKELINK.EXE, with which you
- create links.
-
- How To Use It
-
- First you must create a file of one or more links with
- MAKELINK.EXE. This is a text file which contains four numbers
- and a filename on each line. The four numbers represent a
- sensitized area on screen. When HLINK runs, it waits for a
- user to click a mouse button or press [Enter]. It then
- examines the file of links and if it finds one line
- with an area containing the current position of the arrow,
- then whatever is on that line is executed, and HLINK.EXE is
- done.
-
- From the DOS prompt, or within a batch or script file,
- present the image which will be used as the HLINK picture
- (often thought of as a menu picture). Then run HLINK,
- followed by the name of the file containing your links.
- Here's an example of a RUN script:
-
- PPCX.EXE ANIMALS.PCX
- HLINK.EXE ANIMALS.CFG
- CLEAR.EXE
-
- In the above example, PPCX projects an image you have created
- called ANIMALS.PCX. We'll assume it is a menu image, with
- pictures of various animals, and perhaps containing the
- names of the animals in text below each animal's picture, and
- also containing a simple line of text to the effect of,
- "Point to an animal and click left mouse button." For this
- example, we must also assume you've already used MAKELINK.EXE
- with ANIMALS.PCX to create ANIMALS.CFG, your chosen filename
- to contain links to various specific animal pictures.
-
- You may be surprised to find out that once HLINK finds a
- link, it is done, and disappears into DOS-land forever. In
- order to proceed with a presentation, you would normally call
- HLINK again, when done running the linked file. One way to
- accomplish this is to link RUN.EXE with a simple script file
- which RUNs the program you want to link, then calls HLINK.EXE
- with it's associated link file again, thereby creating a
- loop.
-
- If a mouse is not available, HLINK still works fine. The
- arrow can be steered with the arrow keys, or number keys. If
- the [Num Lock] key is on, pressing any number other than 5
- will move the arrow in large leaps. The numbers [7], [9],
- [1] and [3] move the arrow diagonally. With the [Num Lock]
- key off, the arrow moves slowly - one pixel at a time.
- [Home], [End], [Page Up] and [Page Down] move the arrow
- diagonally. Press [Enter] to simulate clicking the left
- mouse button. You might consider putting this information
- about the arrow movement keys in an early instruction picture
- in large presentations.
-
- Additional Information
-
- NOTE: Also see MAKELINK.DOC for more information about
- Hyperlinking.
-
- If the user clicks where two sensitized areas overlap,
- then the first one in the link file is the one which will be
- executed.
-
- HLINK can also run .COM files and .BAT files, but it
- cannot display text or graphics files directly. It must run
- programs which will display text or display graphics.
-
- Filename extension is not usually required. You can type
- PGIF or PGIF.EXE, for instance, and the effect will be the
- same. In the case where there are more than one file with
- the same name, but different extensions, then .BAT files will
- be run instead of .COM or .EXE files, and .COM takes
- precedence over .EXE.
-
- HLINK can handle optional parameters for the programs it
- runs of up to about 60 characters in length. Maximum line
- length in the links file is 100 characters, including the
- position coordinates.
-
- There is no limit to the number of programs HLINK can
- handle, and no limit to the size of the file listing these
- programs, but MAKELINK is limited to 100 links. In the
- extremely rare case where you would want to have more than
- 100 links per picture, you can use MAKELINK to create two
- files of links, then combine them into one with a text
- editor. A more reasonable solution would be to link
- sub-menus, so that each level would contain only a reasonable
- amount of links.
-
- HLINK.EXE can be executed from within other programs, and of
- course, you can execute programs from within HLINK. HLINK
- supports all standard text and graphics modes.
-
- You can create or modify link files directly if you prefer.
- Use your favorite word processing or text editing program
- which works in standard ASCII mode. If you have Microsoft
- Windows, you'll find the included NOTEPAD program does this
- well. Here's what you have to know to edit link files:
-
- *Each line in a link file contains four numbers, followed by
- a filename and perhaps optional parameters.
-
- *Each line must start at the leftmost position on the screen,
- there can be no spaces.
-
- *Each line is independent of other lines.
-
- *There must be no blank lines.
-
- *Each line starts with 4 numbers separated by spaces.
- They are coordinates marking a rectangular region on the
- screen. The measurements are in pixels, ranging from 0 at
- the top and left, to full-screen size at the lower right. In
- the case of 16-color VGA, for instance, the lower right
- corner would be 639 and 479.
- If the user clicked a mouse button or pressed [Enter]
- when the arrow was within the rectangle, then this is the
- line which will be executed.
- The first number represents the left edge of the
- sensitized area. The second number is the top boundary. The
- third is the right edge boundary and the last number is the
- bottom.

- About Pieces
-
- PIECES is a shareware disk containing several small programs
- that can be combined to do a variety of tasks with
- a super-professional look and feel. No programming experience
- is needed. PIECES can be expanded to incorporate your
- favorite programs as well, so it's possibilities for making
- and enhancing pictures shows, text presentations, multimedia,
- electronic catalogs, teaching materials, executable software,
- games, shareware and more are limitless!
- You can register as many or as few PIECES as you wish.
- Registered users are licensed to copy and distribute the
- PIECES along with their finished products. Unregistered
- users may copy and distribute the complete unmodified PIECES
- package, but may not use only portions of it until purchase
- of registration. Use of PIECES beyond 30 days requires
- registration.
- Most unregistered PIECES programs have a "unregistered"
- notice which pops up randomly, approximately every 200 times.
- This is removed from the registered versions, and also saves
- as much as 3,000 bytes disk space per program.
