>>If you routinely have to modify a lookup table (slight changes to descriptions, add additional values, etc.), make it a lookup table. Don't tell me your users or customers are 100% thoughtful and precise (and not flaky) so when they tell you about data suitable for a lookup table that it won't change in the future (like within about 3 days after delivering the app).

Sorry. If you would have need to modify or add additional choices to a combobox, then put the choices in a lookup table instead of a hard-coded array or hand-entered choices. The original question was when should a lookup table be used versus hand-entered choices (hard-coded). I strongly believe lookup tables should have a primary key (integer) field and a description field with the pk being the stored value in the data tables NOT the description -- descriptions can change causing a big mess in your data tables.
