Issues of The Mathematica Journal may include electronic documents associated with material in the The Mathematica Journal. Online subscriptions contain Mathematica^® programs that can be downloaded and executed with versions of Mathematica on any computer system.

Except where indicated, electronic files in The Mathematica Journal are of two types:

• 1. Mathematica packages containing Mathematica source code, which can be read directly into any version of Mathematica using <<filename, and
  
• 2. Mathematica Notebooks containing text mixed with Mathematica source code, intended primarily for use with the Mathematica Notebook front end.

Both types of files contain only printable ASCII characters, and can thus be transferred and stored on any computer system. Notebooks contain text and Mathematica source code, together with formatting directives. Source code distributed is intended for use with the Mathematica Version 3.0.
