- Thank you for your interest in the Look & Feel (tm) Screen Designer!
- Please feel free to make copies of the the Look & Feel demo and pass it on
- to others.

-
- This disk contains the file lnfdemoz.exe, a self-extracting archive with the
- Look & Feel demo in it. We suggest that you create a demo directory on your
- machine and copy lnfdemoz.exe to that directory. Change to your demo directory,
- then type:
-
- lnfdemoz
-
- This will un-archive the demo and the files that it uses, copying them into
- your demo directory.
-
- To run the Look & Feel demo, type:
-
- lnfdemo
-
- If you wish to run the Look & Feel demo in monochrome mode, type:
-
- lnfdemo -m
-
- The demo will show and explain some of Look & Feel's features. It shows some
- simple screens being created and tested. Source code is generated for one
- of the screens. You can look at the generated source in the file one.c.
- When the demonstration is finished you will be able to try out Look & Feel
- on your own.
-
- To explore Look & Feel without running the playback demonstration, type:
-
- lnfdemo -d
-
- When using Look & Feel, you can call the main menu by pressing F10.
- This allows you to use any of Look & Feel's features. You can call the help
- system either directly by pressing F1 or by selecting it from the main
- menu. You can load sample screens from the file sample.lnf using the
- Disk-Load command. For example, to load the piano screen:
-
- (1) type F10, D, L to get the Screen Load Box,
-
- (2) type "sample.lnf" in the file field,
-
- (3) type "piano" in the screen field, and,
-
- (4) press ENTER in the OK field.
-
- You can play the piano by using the Screen-Go (F9) command and typing
- in the letters on the piano keys.
-
- This demo version of Look & Feel is identical to the actual version with the
- following exceptions. It cannot generate source code and its file saving
- functionality is limited. You can only save screen "demoscr" to file
- demo.lnf.
-
- The demo was created using C-scape's keystroke record and playback facility.

- About Look & Feel
-
- The Look & Feel Screen Designer is a visually oriented screen designer
- and code generator. It provides a simple and powerful method for creating
- and modifying screens, so you can use it to experiment with various
- interfaces for your applications before selecting a final one. Look & Feel
- is a powerful design aid for both programmers and non-programmers.
-
- With Look & Feel, you can create titles, data entry fields, text editors, and
- menuing systems (including pulldown and nested menus). Screens can also be
- larger than your display, as Look & Feel supports vertical and horizontal
- scrolling. Since Look & Feel is a "wysiwyg" editor, the screens you draw
- will look the same as the screens you will have in your finished program.
-
- Within Look & Feel you can also:
-
- * Use all standard C data types including structures and arrays
-
- * Edit in multiple windows
-
- * Move, cut, paste, and copy fields and blocks
-
- * Use on-line, context-sensitive help
-
- * Simulate the operation of all designed screens and menus without
- compilation
-
- * Link your own functions into Look & Feel to customize its simulation
- capability.
-
- Each screen you create will contain fields. Most fields are data entry areas.
- Look & Feel provides over thirty functions to govern field behavior, and you
- can also include your own custom functions. You can also assign variables,
- prompts and commands to fields, and validate their data.
-
- When you complete a screen, you can save it to disk in an .lnf file. You can
- also load ASCII files or files from Dan Bricklin's (tm) Demo Program and
- save them in the .lnf format, allowing greater flexibility in prototyping.
- Screens in .lnf files can be called from a program at run time, which helps
- shrink executable code size. By using .lnf files, you can change an
- application's screens without recompiling.
-
- You can also use Look & Feel to convert finished screens to C code, which you
- can read and alter as you please. You can even port the code--without
- modification--to any environment supported by the C-scape (tm) Interface
- Management System. This code calls C-scape library routines to create a
- function that displays the screen, handles data entry and other functions,
- and returns the data to the calling routine.
-
- Because Look & Feel has a complete text editor, you can generate code and
- edit it without leaving the program. The editor allows you to perform
- searches, search and replace operations, and block operations (such as copy,
- delete, paste, and cut).
-
- The source code for Look & Feel is available directly from Oakland Group.
-
- Since Look & Feel was built using C-scape, this demo also serves to exhibit
- C-scape's various features, and how they can be used.
-

- about Look & Feel or any other Oakland products, please call us at
