Press Release

Tuesday 2/21/89

Delta Research proudly announces the release of:

    JForth Professional - Version 2.0

The most significant new feature of JForth 2.0 is Clone,
the "Optimizing Target Compiler".  Clone examines a
compiled Forth application, and build a new executable image
containing only the code and data needed.
Clone can create applications as small as 3K.
Size and execution speed compares favorably with 'C' programs.
Cloned programs may be distributed without royalties.

Other new features include:

.lm +2
Source Level Debugger with breakpoints, and single step.

Precompiled, dynamically linkable modules for 'include' files,
and the Assembler and Disassembler.  Now structure definitions
won't take up space in your dictionary.

Hashed Dictionary for 2-8 times faster compilation.
Small programs compile in a few seconds so your productivity
is improved.

Command Line History like the Amiga DOS Shell (built in
so that the Forth word KEY works properly).

User Assignable Function Keys.

IFF Support for read and write, plus simple bitmap animation system with
blits, wipes, and fades. This makes it easy to use
images from paint programs in your applications.

New Forth Vendor Group Standard 32 bit FFP and 64 bit IEEE Floating Point
using Amiga libraries.
Support for transcendental functions, enhanced number formatting,
plus many optional extensions.

ODE, the Object Oriented Development Environment, now allows
nested objects as "instance variables".

Numerous new tools and utilities including Serial I/O, sample
applications and new graphics demos, documentation generator,
etc.

The new manual includes many new tutorials and an expanded
reference section.
.lm -2

JForth is a 32 bit, '83 standard Forth.
It is an interactive programming environment
that allows you to call any routine or examine
any data structure interactively.
Small programs can be compiled in a few seconds for fast development.
Unlike traditional Forths, JForth compiles directly to 68000
machine code for significantly faster execution speed.
JForth allows you to call any Amiga
library routine by name, completely insulating
you from the details of 68000 register assignments, etc.
Amiga structures can be referenced with automatic sizing
and sign extension like in 'C'.
Programs can be written
using either normal text files or traditional
BLOCK files.

(An example of JForth code can be found in Amazing Computing,
Dec. 1988, p79.  Look for public domain Cloned JForth programs
on the nets.)

JForth Professional 2.0 is available from retailers at
a suggested list price of $$179.95.  Registered JForth 1.2
users can receive a full upgrade to 2.0 for $$50.00
AND the ORIGINAL "EXTRAS" disk (the one with the executable
JForth image).
A "Clone Only" upgrade is also available for $$10.00
for one disk with documentation on disk.  We strongly recommend, however,
that people get the full $$50 upgrade because of the other new features.
(A new HMSL disk that uses the new JForth features
is available to registered HMSL users for $$10.
HMSL is an experimental music language based on JForth.)
