Thanks for the quick review, Kim. Attaching a second rev of the patch with accompanying tarball: derby-4737-02-ab-types-assignments-casts.
I agree that the examples look better with a title, so I added one as you suggested. I was a little puzzled that there was no title for the examples section on the reference page for the data type which I used as my template (BIGINT). Some of the data types have titled examples (e.g. CHAR), and some don't. Maybe worth a cleanup on a rainy afternoon.
Vis-a-vis the hobgoblins, I think I will stick with my perverse camel-casing. Thanks.
