Forth is an interactive software development environment,
normally tailored for embedded controller and machine
control applications. With JForth's comprehensive Amiga
system interface, Forth now excels at platform software
development. Originally created to provide precise control
of observatory telescopes, Forth contains both an interpreter
AND a compiler, combining the best features of both systems.
The interpreter affords interactive access to all language
features; programs are compiled into native 68K code. JForth
programs are compatible with all AMiga models and OS
versions. AGA support (3.1) is currently in beta test.
This is a demo version of the JForth Professional 3.x
software development system. It includes a complete
JForth interpreter/compiler which is fully-functional
but limited in the size of executable code it will
produce. Also, the demo will NOT create standalone
programs (the commercial package will). This demo
version also offers an "Introduction" which can be
optionally viewed at startup.
The demo interpreter/compiler includes a disassembler,
assembler, as well as a source-level debugger. While
the demo package does not provide the JForth "include"
files (similar to C's ",h" files, JForth calls them
".j"), MANY are pre-compiled and accessible in the demo
program. Similarly, the demo can also call many Amiga
shared-library functions, as they have been pre-compiled
for you (the demo package does NOT support adding more...
the commercial package can call any Amiga library func-,
tion, even custom libraries).
Additionally, there is a compiled example program which
demonstrates the JForth interface into graphics, menus,
HAM mode, gadgets, etc.
There are several source files provided, including an
IFF file viewer, word/line counter and others (all will
compile within the working space limitations imposed by
the demo). Additionally, several tutorials are provided
for users new to Forth and/or JForth.
Also provided is V1.11 of Textra, the user-friendly
Amiga GUI-based text editor. This is the same editor
which accompanies the JForth package and can be
integrated with JForth (even the demo) via ARexx.
(Later versions of Textra are available and are
completely backward-compatible with JForth).
Finally, as an example of a JForth standalone,
graphics-based productivity application, Mike Haas'
1993 "LCD Calculator II" is included.
