These functions are indeed easy to implement. The following notebook,
with Output removed for brevity, shows one way to make them. Paste the
notebook into Mathematica 3 or Mathematica 4. (Differences between these
two version are relevant to this task.)

                    Mathematica-Compatible Notebook

This notebook can be used on any computer system with Mathematica 4.0,
MathReader 4.0, or any compatible application. The data for the notebook

starts with the line containing stars above.

To get the notebook into a Mathematica-compatible application, do one of

the following:

* Save the data starting with the line of stars above into a file
  with a name ending in .nb, then open the file inside the application;

* Copy the data starting with the line of stars above to the
  clipboard, then use the Paste menu command inside the application.

Data for notebooks contains only printable 7-bit ASCII and can be
sent directly in email or through ftp in text mode.  Newlines can be
CR, LF or CRLF (Unix, Macintosh or MS-DOS style).

NOTE: If you modify the data for this notebook not in a Mathematica-
compatible application, you must delete the line below containing the 
word CacheID, otherwise Mathematica-compatible applications may try to 
use invalid cache data.

applications, contact Wolfram Research:
