To Robert Bozick:

Try this:
gen newvar = "z1" if oldvar1 == 1 & oldvar2 == 1

Properly, this is...
gen str2 newvar = "z1" if oldvar1 == 1 & oldvar2 == 1

but with Stata 8, the -str2- is optional.

Note that this does it all in one step; no need to first load newvar with null strings. But if you prefer, you can do...
gen newvar = ""
replace newvar = "z1" if oldvar1 == 1 & oldvar2 == 1

I hope this is what you were looking for.

Hello -

I am having a simple problem. I am trying to create a string variable based upon a number of conditions.

The gist of the code is this:

gen newvar = .
replace newvar = 1 if oldvar1 == 1 & oldvar2 == 1

This produces 16 cases where newvar = 1, which is exactly correct.

However, I don't want newvar to = 1, I want it to be a string character z1. If oldvar == 1 & oldvar2 == 1, I want newvar to take the string value of "z1" --- How do I go about doing this? I know this is really simple, so thanks in advance!
