(See http://support.wolfram.com/Systems/Student/Differences.html) Also, writing packages in Mathematica 3 is a pain because of the bugs in the Front-End (at least that's my experience on a Mac). Mathematica 4 is much better in this respect. Though, once I used the Save As Packages command, Mathematica had problems writing the package (the .m file was corrupted). Mathematica reported about this problem. However, in my panic I saved the notebook (which was also corrupted at that point) and, therefore, overwrote the (probably) intact version of the notebook on the hard disc. Thus, I lost one days works (luckily I had a backup from the day before). The big advantage of writing a package with Mathematica 4 is the bracket highlighting. (However, many word processors can do that also.) Considering all this, my recommendation is the following (which is what Roman Maeder also recommends in one of his books): Develop the package as a set of functions within Mathematica (without the context stuff) and when it is (almost) finished, put it into a word processor (Save as Text) and do the final editing there.
