see -help strfun- (help for string functions) and check out -index()-

This will return the position in the string of the first character of the sought keyword or else 0 if the keyword does not exist within the string. To turn this into a 0/1 dummy, you might

gen byte kw_found = index(stringvar, "keyword") > 0

where kw_found is the new 0/1 dummy variable and stringvar is the name of the string variable in which you seek the occurrence of "keyword".

Dear all,

I too am relatively new at STATA, trying to find my way around the differences in the syntax language from SPSS.

Anyway, I was wondering if there was a way in STATA syntax to search a string variable for keywords and create an indicator variable (dummy) where 1=keyword found and 0=keyword not found?

Thanks in advance,
