- WELCOME TO THE JFORTH DEMO DISK!
-
- This is a demo of JForth Professional V3, one of the most
- powerful and sophisticated flavors of the Forth programming
- language available.
-
- EVEN IF YOU ARE NOT A PROGRAMMER, this disk will benefit you,
- because we've included 2 commercial-quality, useful applications.
-
- First, there's TEXTRA V1.11, the user-friendly text editor
- with ARexx (plus documentation and ARexx scripts). This is
- a general purpose, standard text editor with a focus on
- ease-of-use. Textra can function as an integrated editor with
- JForth via ARexx.
-
- Also included is the LCD Calculator, which was noted in
- mid-1991 issues of both AmigaWorld and .INFO (the latter
- even displayed a screenshot). (Please note that the LCDIFF
- drawer must reside either in the same drawer as LCD
- Calculator, or in sys:utilities). (NOTE: This demo contains
- the newer LCD Calculator II program, which includes printing
- and a color requester!)
-
- Feel free to distribute this disk, including TEXTRA and the
- LCD Calculator to user groups and your friends, but PLEASE pass
- this disk around in its entirity!
-
- (Incidentally, TEXTRA and LCD Calculator are both written in
- JForth; they are standalone programs produced with the CLONE
- facility, one of JForths many unique and advanced features.)
-
- For those that ARE interested in programming, this disk should
- prove a treat! It contains a functional but limited JForth
- compiler and interpreter in conjunction with example programs,
- tutorials, and a compiled "Introduction" program available in the
- JForth program startup.
-
- The "Example_Program" executable is another CLONEd JForth
- program. It utilizes many Amiga facilities such as graphics
- (including a HAM mode demo), menus, sprites etc. The JForth
- source code for "Example_Program" is not provided with this
- demo, but does come with the JForth product release. These,
- as well as the source for other 'demos' in addition to some
- real, useful tools (such as 'wordcount.f ', which IS
- included in this demo package) provide the customer with a
- multitude of example JForth-Amiga programming techniques for
- accessing your Amiga's Intuition, graphics, menus, ARexx,
- and animation capabilities and more.
-
- The standard JForth product includes complete Amiga 2.0 include
- support files, in JForth '.j' form, as well as the means for
- accessing all standard and custom Amiga shared-libraries.
- While the include files are not included in this Demo compiler,
- many Amiga data structures and system calls have been pre-compiled
- for you. Their use is described in the "Tutorials/Tutorial" file.
-
- With this demo, you can compile and examine the provided
- source code programs and get a feel for programming in
- Forth. You can observe the crisp, immediate aspect of the
- JForth interpreter, allowing "direct access" to all levels
- of the machine. Hopefully, you will appreciate the
- interactivily of the language, allowing you to compile
- high-level programs from the keyboard, and examine, even
- execute subroutines individually in the same manner. The
- compiled Source-Level Debugger may be be of interest. Or
- opening windows and making graphics calls one-at-a-time from
- the keyboard... INTERACTIVELY!
-
- Anything is possible with Forth... JForth!
-
-
- To get the most from this demo, may we suggest...
-
- o Play with the "Example_Program"
-
- o Run the "JForth_Demo" program and view the 'Intro' program.
-
- o You may want to run your Amiga in Hires-Interlaced mode,
- so that both your text-editor/viewer and JForth may be
- easily visible at the same time. OR...
- Some may prefer to print out the tutorials to follow with
- hardcopy, perhaps taking notes (The Textra editor will
- print text files, paying attention to the system Printer
- Preferences AND with optional line numbers and/or a 'page
- header' line at the top of each page).
-
- o Pathnames in the tutorials & intros are relative to the
- topmost directory, the one containing the "JForth_Demo"
- program. (If you launch it from shell, you should CD to
- the same directory as the program. If you double-click
- the "JForth_Demo" program, this is automatically the
- case).
-
- o View the text files in the 'Tutorials' directory in this
- order...
-
- 1. Overview
- 2. Tutorial
- 3. Grand_Tour
- 4. More_Commands
-
- o INCLUDE each of the files in the 'Programs' drawer, and play
- with them, disassemble parts of them, look at their source
- code.
-
-
- We hope you enjoy this JForth Demo.
