Picture Creation
----------------

Introduction

     This program is designed to help you learn about the graphics symbiosis 
system (GRASS). The intention is to provide you with the fundamental knowledge 
and skills necessary to allow you to use the system. It is not intended to 
provide you with a complete description of all the possible ways in which the 
system could be used. That would be impossible because the uses of the system 
are limited only by your own imagination.

     There are three parts to this program. Depending on your present knowledge 
of the system, you may wish to go through all, or only some, of these. The 
first part will teach the commands, and allow practice in the skills necessary, 
to create pictures. The second part will do the same for picture manipulation. 
The third part will be on "macro" writing. Each part will assume knowledge of 
the proceeding parts.


     The eighteen pages are broken into six sections:
