Hallo NG,

I'm running Mathematica 3.0 on NT4.0

I wrote a package using the Collatz example in the Mathematica book chapter
2.6.10 as a template.

2. Switched that cell to be initialization cell.
3. Saved special as package format with name package.m (If I didn't switch
to initialization, Mathematica wrapped two (*  *) around the whole
 As far as I see, everything works fine. But is this the common way to write
packages? To me the procedure is a bit strange, although it works. Any
