Pocket Forth, version 0.6.5 by Chris Heilman 9/30/95

Introduction

Forth is a beautiful language. It is easily spoken and source code looks like
poetry. Oh yes, Forth produces fast compact code. Pocket Forth is a small
Forth system for the Macintosh computer, founded on well documented
principals(1,2,3). Although Forth is being standardized, Pocket Forth has
evolved independently of the standard.

Pocket Forth is based on Flint by G. Yates Fletcher(4), figFORTH(5,6) and the
Forth described in Starting FORTH by Leo Brodie(7). I wrote Pocket Forth to
experiment with the Macintosh toolbox and Apple Events. Pocket Forth can
produce applications that run under any system version.

Programs are easily modified and you are encouraged to adapt Pocket Forth into
your own program. Toward this end, you own your copies of Pocket Forth.
Programs may be distributed with no royalties, homage, or other restrictions,
even if the Forth system is available to the end user.

NOTE ╤ Pocket Forth is not warranted for any particular purpose. That means
you assume all of the responsibilities in the use of Pocket Forth.

I have attempted to make Pocket Forth free of bugs, but low level languages,
such as Forth, allow you access to the operating system. Therefore, use Pocket
Forth with care in conjunction with other programs or files. This is
especially true when writing programs that access the disk, or when
experimenting while using other programs that do. Always open a backup of any
file you may want to keep, including Pocket Forth itself. Never run originals!

If you are new to Forth, read Starting FORTH to learn the language. The
Starting folder (inside of the Extensions folder) has more information on
using Pocket Forth with Starting FORTH to learn the language.

Preparation

To use Pocket Forth, follow this procedure:

е Back up Pocket Forth before running it. Put the original away and make a
working copy. Be sure to run the working copies only.
е Double click the program's icon. If everything is ok, a window will appear
and say so. The 'ok' prompt and cursor indicate that Pocket Forth is ready for
input.

Use other programming utilities, such as resource editors, to provide a rich
programming environment.
