Thanks for the feedback.  I do have in my presentation notes that the entire
vocabulary fits on one page - I meant to emphasize that what I show is a
sample, so I should mention the size of the "population".

When I'm talking about "compact", I was thinking of writing a Newton solver
in one line but it wouldn't hurt to mention the small size of the
interpreter + libraries as well.   I estimate this as about 2.7MB for the
interpreters and dlls plus about 22MB for the addons, as well as about
17.5MB for the system, tools, help, and icons directories for a total of
42.5MB - still svelte by modern standards:

   +/ 2723080 22323739  NB. bin/j.exe, jconsole, jnative, jee, j.dll, j.jar
+ addons
25046819
   +/ 6926980 856946 9184784 573168 NB. j602/system, tools, help, bin/icons
17541878
   +/ 25046819 17541878
42588697

I'll see if I can wedge in a few more elementary examples though I have less
than 50 seconds per slide.

Good catch with the missing negative sign - another cut-and-paste "droppo".

I'll post an updated version in an hour or so.
