Sorry about the typo:

gen byte newvar=substr(sequence,1,4)=="Tim "

I don't see any need for a wildcard; how about

gen byte newvar=substr(sequence,1,4)=="Tim"

Hi Statalisters,

I am not sure how the string wildcard works. For example, I have a
string variable called "sequence" that has the following

1. "Tim and Tom and Jane"
2. "Tim and Jane and Tom"
3. "Tom and Jane and Harry"
4. "Jane and Jill"

I want to generate a new variable that equals one if Tim is the first
name mentioned, and zero otherwise.

Thanks in advance,
