demonstration disk and is not intended to fully document OPAL
and its features. A printed manual, plus other benefits come
with OPAL when ordered. For further information refer to the
section on registration later in this documentation.

If any portion of the demonstration disk is missing, a
complete demonstration disk is available for $10. Use the

OPAL INTRODUCTION


PURPOSE

OPAL is a rich, full-functioned batch executive language that
frees you from the limited capabilities of BATCH and other
primitive executive languages found at the microcomputer
level. It is designed to assist quick and flexible
application development. OPAL makes it easy to gain the
control you need over your DOS applications. OPAL can CALL
virtually any other software that runs under the DOS
environment. OPAL understands how to work with and enhance
your DOS environment and applications.

But, OPAL offers much more than just DOS compatibility. OPAL
is a full-fledged language with more functions than you would
ever expect from a batch executive language. And, as an
interpretive language, no compiling is needed to run OPAL
routines. Thus, OPAL allows you to prototype program
functions and user interfaces without having to recompile each
time the prototype changes.

OPAL offers a flexible, versatile alternative. In these ways,
and more, OPAL dramatically reduces your application
development time. And, the applications you develop are more
efficient, easier to maintain, and easier to use.





THE USER-SUPPORTED CONCEPT

User-supported Software

User-supported software is an experiment in distributing
computer programs based on these beliefs:

1. That the value and utility of software is best assessed by
the user on his/her own system.

2. That the creation of personal computer software can and
should be supported by the computing community.

3. That copying of programs should be encouraged, rather than
restricted.

Anyone may legally obtain an evaluation copy of the program
from a friend or computer club. After you have had a chance
to use and evaluate the program in your own environment, you
are trusted to either forward a payment to The Software
Factory or to discontinue use of the program.

Free distribution of software and voluntary payment for its
use eliminates costs for advertising and copy protection
schemes. Users obtain quality software at greatly reduced
cost. They can try it out before buying, and do so at their
own pace and in the comfort of their own home or office. The
best programs will survive, based purely on their quality and
usefulness.




RESTRICTED PERMISSION TO COPY


Individuals are granted permission to freely copy the OPAL
disk for their own use or for others to evaluate, so long as
no price or other consideration is charged.

Computer clubs and other non-profit organizations are granted
permission to freely copy the OPAL disk and share it with
their members, so long as:

1. No price or other consideration is charged. However, a
distribution cost may be charged for the cost of the
diskette, so long as it is not more than $5 total. This
includes shipping and handling charges.

2. Club members who receive the programs are informed in
writing of the user-supported concept and encouraged to
support it with their payments.

3. The programs and documentation are not modified in any way
and are distributed together.

4. The OPAL disk may not be packaged together with any other
programs or materials. It may not be bundled and sold as
part of some other more inclusive package.

5. The programs may not be "rented" to others.

6. The printed manual may not be copied or reproduced in any
way.

Companies, schools, universities, government and other
organizations are granted permission to copy the OPAL programs
for use on other computers and at other locations in the
company so long as:

1. The full registration fee of $59.95 has been paid for each
and every system on which the program will be used.

2. The printed manual may not be copied or reproduced in any
way.

Corporate licenses and volume discounts are available upon
request.

EXECUTING THE DEMO

To try out the demo, simply type DEMO at the DOS
command prompt.


EXAMPLE DESCRIPTIONS

These examples are here for your review and improvement. They
are written by different individuals and therefore contain
different programming personalities. It is our hope at The
Software Factory that these examples aid you in some way, even
slightly.

- MISC

The Miscellaneous Example Program Shell shows how utilize OPAL
as a application manager. To run this application program,
OPAL needs to be in the current directory or on an environment
path.




- MAKEIT

The Makeit Utility has found a home at The Software Factory as
a tool for creating DOS Batch files with a constant prefix and
suffix. Some older programs do not support wildcards for
filename input, making it necessary to duplicate the same
command over and over again.

In other cases all of the commands may be the same but a
couple of the options need to be changed, that is the reason
for the editor in Makeit.

If nothing else, Makeit show how to spawn different tasks and
uses a form with an edit_action.

- MILLIONS

This program was rewritten from a similar program written in
the C language. The program is used to determine how long it
takes to become a millionaire. It demonstrates OPAL's
usefulness as a quick programming aid.

- HOWOLD

Did you ever want to now how old something was in terms of not
only years, but, Quarters, Weeks, Days, or even Seconds.
Howold uses OPAL's time stamp functions to calculate different
time periods. Do you now how old you really are?

- HANG

The ever popular Hang-Man Game. HANG uses OPAL's menu
capabilites to build a alphabet menu. You select or guess a
letter and pray you don't get hung. The author has chosen
some unique words and you are free to add to the dictionary or
change it if you know them all.

The program is also a good example of structured programming
and makes for some interesting learning.

- RADIX

Have you ever needed the radix of a number and been without
SIDEKICK or your HP. Don't fear OPAL's Radix is here to give
you the Binary, Octal, Decimal, and Hex equivalents of a given
value.




- CRITICAL

One of the factors used in evaluating the effectiveness of a
ramp leading to a highway is the Critical Gap. It is assumed
that a driver waits on a ramp until he estimates a time gap
between successive vehicles which he regards as sufficiently
long for him to safely enter the traffic stream. This
Critical Gap is a function of the angle between the ramp and
the highway, and the length of the acceleration lane.

The angle is entered in degrees. The acceleration lane is
entered as a normalized length, i.e. /100

A shape factor is available for Tapered or Parallel ramps.

This example OPAL program calculates the length of the
critical gap, T in seconds. T is a function of TH, the angle
between the ramp and highway ; D, the normalized length of the
acceleration lane; and S, the ramp factor.

- TOWERS

The Towers of Hanoi problem has an initial setup as shown
below:

A B C
| | |
[*****] | |
[*******] | |
[*********] | |
[***********] | |
--------------- --------------- ---------------

Three pegs exists, labeled A, B and C. Four disks of
differing diameters are placed on peg A so that a larger disk
is always below a smaller disk. The object is to move the
four disks to peg C using peg B as auxiliary. Only the top
disk on any peg may be moved to any other peg, and a larger
disk may never rest on a smaller one. Can you solve this
problem? OPAL does it using a local routine and recursion!
