[REBOL] debugging rebol apps Re:(2)

Incrementally. Each time I make a change that I think is
trivial, I still go make sure it works as expected. I break
out common code into functions, and then debug those functions
individually. Always add type specifiers to function arguments
to be sure you're being passed what is expected.
The thing that always seems to help for me is I'll try to make
each module do something very simple successfully before
elaborating. Like, for instance, if the goal of a function is
to generate some data and then display it (or have another
function display it) I make my first goal to successfully:
print mold data
When a script reaches the couple pages mark, I find it helps
to break out common parts, like utility functions, to go into
their own file. They can always be recombined later, but the
more scrolling you end up doing the more confusing it can become.
Nothing revolutionary in those approaches, but I find them
helpful in building larger apps.
