Version 2.1

Copyright 1989 by Norm Draper

For the Atari 400, 800, XL, or XE series computers

Disk Based Documentation#

This document contains the "Getting Started" section plus other sections from the actual Draper Pascal manual. It is designed to get you up and running and doing useful things with Draper Pascal in a very short time. It does not, however, contain a detailed description of all the Draper Pascal definitions or pretend to be a comprehensive tutorial or user's reference. Registered users will receive the actual Draper Pascal manual which does contain a complete description of all definitions plus other information. Details on registering are in the last section titled "Registration Form".

The Shareware Concept#

Draper Pascal is distributed on a Shareware basis. You may use Draper Pascal without charge for the purpose of evaluating it's suitability for your use. If you find that Draper Pascal is worth continuing to use, then you are requested to become a registered user and gain the additional benefits that go along with it. Simply complete the registration form and mail it in to us with the very reasonable payment of only $15.00. When you register your copy of Draper Pascal, you'll receive the latest version of the software if your registered version is not current, along with a comprehensive printed user manual.

If you have received this copy from a Users' Group, "Software Library" or "SIG", and have paid a small fee (usually $3 to $10), you have NOT acquired the registered rights or continued right to use Draper Pascal. This fee was for the convenience of obtaining the diskette with Draper Pascal on it. The fee does NOT apply to the registration fee.

You may freely copy Draper Pascal for distribution under the Shareware concept, without charge.

You may NOT charge any fee for the Draper Pascal program or documentation without our written approval.

You may NOT distribute Draper Pascal or it's documentation in connection with ANY commercial venture, product, publication or service unless you obtain the royalty-free license by registering.
