[From Dag Forssell (931220 2150)
It has taken more than just a few hours, but I have at last compiled
a floppy disk that holds all the PCT demo programs I am aware of and
a number of educational postings from CSGnet. I will send the disk
directly to anyone, anywhere, who sends me $10 to support my work and
offset shipping costs. I am also sending a disk to Bill for his blessing
before it goes to Bill Silvert for addition to his listserver.

READ_1ST.TXT:
PERCEPTUAL CONTROL THEORY
Demonstrations, tutorials, simulations and explanations
Disk prepared by Dag Forssell December 20, 1993
This disk may be freely copied. It has been prepared for the purpose of
evaluation, self-study, teaching, research of Perceptual Control Theory,
and as a supplement to the Purposeful Leadership seminars.
This disk holds several executable demonstration programs and documents
in separate directories as shown:
A:\ Floppy disk drive. (READ_1ST.TXT)
---ARM1\ Little Man version 1. With explanations.
---ARM2\ Little Man version 2. With instructions.
`SOURCE\ Source code for Little Man version 2.
---CROWD\ Crowd program. With instructions.
---DEMO1\ Self-guided control theory tutorial #1.
---DEMO2\ Self-guided control theory tutorial #2.
---ECOLI\ Simulation of bacterial chemotaxis.
---PCTDOCS\ Explanations and discussion from the CSGnet.
---SIMCON\ Simulating analog control. With tutorial text.
`---SPRDSHT\ Hierarchical control simulation. With explanation.
`ASEASY\ A shareware spreadsheet.
Each directory holds a self-extracting archive file which holds files
and programs in a compressed, space saving form.
Each directory also holds a file with initial instructions, ending
with .RD. Read this file first, using your wordprocessor or the DOS
EDIT utility.
The .RD file explains the function of the third file in each
directory, which is an INSTALL?.BAT file provided as an option.
Many documents contain figures created on the computer screen using
the ASCII characters found on the keyboard. An ASCII diagram can be
distorted when printed if you have a printer with proportional
spacing, justification and kerning. Print in a small font with
constant pitch, such as courier, left alignment and no kerning, in
order to have everything line up right.
As of December 1993, there are no fees for studying, using and
teaching with these programs. They are generously provided by
William T. Powers, Rick Marken (Spreadsheet model) and Wolfgang
Zocher (Simcon) for the purpose of self-study, teaching, and
research of Perceptual Control Theory.
The commercial shareware program AS-EASY-AS is not free. The files
explain the rules for trial use and registration of shareware.
This disk is prepared as a 3 1/2 inch high density disk. The files
occupy 1,286 Kb. To copy to a 5 1/4 inch high density disk, please
move the ASEASY directory to a separate disk. The disk can also be
divided into several low density floppy disks by copying individual
directories. If you do, please copy this file to each disk as a
listing of what is available.
Enjoy!

As a sample, here is DEMO2.RD from the DEMO2 directory:
The programs in this directory (DEMO2) are in a compressed, self-
extracting file called TUTOR2.EXE. (This is a the second tutorial
program). This file, when executed, will expand itself into many files,
including the "real" executable file DEMO2.EXE.
For your convenience, an INSTALL6.BAT file is provided which will give the
DOS commands to install this program on your C: drive in its own
directory: While in this directory, type INSTALL6 <ENTER> and the
INSTALL6.BAT file will create a directory C:\PCTDEMOS\DEMO2\ on your hard
drive, copy the file TUTOR2.EXE there, execute it to expand it into 29
files with a total of 194,829 bytes, then delete TUTOR2.EXE (on the C:
drive, not on the originating floppy disk). The runnable program is then
DEMO2.EXE.
Of course you can move TUTOR2.EXE yourself to a directory of your choice
on a hard or floppy disk and expand it and delete it yourself.
The program requires a mouse, joystick or analog-digital converter board,
(see APPENDIX.A). Be sure it is installed before running DEMO2.
The first time the program runs it will create "SINCOS" (16,384 bytes),
then "MAINDIST" (163,860 bytes), a table of disturbances. There will not
be room on a 360 Kb floppy disk for MAINDIST unless you delete the
DEMO2.DOC manual on the working disk before you execute DEMO2.
Also, the initial run asks for configuration information to fit your
hardware and creates the file "ADCONFIG" (33 bytes). If you want to
change the configuration later, delete the file ADCONFIG and restart the
program.
To print out the manual, type "TYPE DEMO2.DOC > PRN" and enter (without
quotation marks -- be sure printer is on), or use your favorite
wordprocessing program to read and print DEMO2.DOC.
To print out APPENDIX A, (If you have not already done so for DEMO1),
type "TYPE APPENDIX.A > PRN" and enter, or use your favorite
wordprocessing program to read and print APPENDIX.A.

Best to all, Dag
P.S. Note to Martin. I can and will write a careful reply to your
personal post. Do you object to my putting it on the net along with
yours? I much prefer communication on the net, not off. By the way,
I am composing an essay on the difference between soft and hard science
which will appear on this net in a few days, now that the demodisk is
done.
