Showing Friendly Values In The GUI

I am new to SQL server and I am looking for the best practice
regarding the following:

The GUI for the database I am creating has a number of questions like:
A. Where are you currently living?
1) In my own home
2) In the home of a family member
3) In a shelter
4) On the street

However, for speed of data entry, the GUI (it's a web front-end,
ASP/VBScript) accepts the number only. Futhermore the database only
stores the number entered.

So for example for the above question, when the user is doing the data
entry, they would just enter a 1, 2, 3, or 4.

However, when viewing the data, the end user wants to see the text
that corresponds to the number. So for example, if the user entered
"3" for the above question, when they are viewing the data in the GUI
(not to make edits, just viewing), they want to see "(3) In a
shelter".

My question is how best to display these friendly values?

Should I do all the conversions in a stored procedure? If so, what
would be the best way to do that? I tried something like this:
SELECT Current_living =
CASE Current_living
WHEN 1 THEN '(1) In my own home with my partner'
WHEN 2 THEN '(2) In the home of a family member'
ELSE NULL
END
FROM tbl_DemographicInfo WHERE ClientID = @ClientID

but I can't figure out how to do this for multiple fields.

ALSO, I'm not sure if burying this stuff in a stored proc is the way
to go, because if the client wants a slight change to the friendly
name I have to get into the SP and change it. Seems like there must
be a better way.

I can also do this in the ASP code, but that also doesn't seem like
the best practice.

I can have a lookup table, but again, where do I do the conversion?
In an SP? With a view?

Again, I'm looking for the best practice here. I know some ways I
could do it (like in the ASP), but I want to do it efficiently and
correctly.

Any help/comments are greatly appreciated.

thanks in advance,
