Sun Forth-83 System

* Parameter and Return stack are 32-bits wide (a compatible 16-bit
  version exists).

* Implements the Forth 83 standard except for no BLOCK I/O

* Unix file I/O used instead of BLOCKs

* Runs both under Unix and stand-alone

* Normal Unix program development facilities may be used for developing
  Forth programs; e.g. Vi, Emacs, grep, make, etc.

* Includes many utilities:
-- decompiler
-- 68000 assembler
-- multi-tasking package (both stand alone and under Unix)
-- 16-bit/32-bit portability package; allows the writing
   of code which will run unchanged on 16 and 32 bit Forths
-- "Standard I/O"-like interface to Unix file system
-- Terminal-independent cursor and screen control package

* Built-in command-line editor provides features similar to
  Emacs for editing command lines as they are being typed.
  Includes command completion for Forth words, like in Tenex.

* Floating point package which implements the Forth Vendor's Group
  proposed floating point standard.  Based on the IEEE floating point
  standard.  Separate floating point stack.

* Has access to Unix system calls and libraries via a companion C program.

* Programs developed under Unix may be run stand-alone on a Sun Workstation.

* Stand-alone programs are easily portable to other 68000 boards; currently
  the system has been ported to more that 5 different 68000 systems. (The
  most recent port took two hours; most of that time was spent figuring out
  how to hook up the RS-232 line to the terminal)

* Stand-alone programs have access to the entire hardware environment of
  the Sun Workstation (they run in supervisor mode).

* System is completely ROM-able.

* Vocabulary search order specifiable at run time using the ALSO/ONLY scheme.

* System is quite mature - it has been in use internally for 18 months.

* System will completely recompile itself.  It is written in Forth and
  a "metacompiler" is included.

* Simple string package.

* Forth words recognized in lower case.
