Pilot programs are run directly from storage RAM, so code size is
not really an issue. The 20K figure is only for dynamic memory
usage: stack space, global variables, allocated 'working' storage,
and so forth... I haven't looked at the zz code closely enough to
see whether this is necessarily a problem or not.
I don't know of any existing hash libraries for the Pilot, but one
of course could be written.
Another issue is user input: the Pilot has no keyboard, but it
does have a touch screen and 6 buttons. It ought to be worth thinking
about to see what the best way to interact with zz via a pointing
device is, as opposed to via lots of keyboard commands.
