Generally on looping, you want to see NJC`s
http://www.stata-journal.com/sjpdf.html?articlenum=pr0005
You might be better off -merge-ing the two files, with a judicious choice of
the options for -merge- "being of the essence"...

Subject: st: Looping through entries in csv file
Hello Statalist,
I have a bit of a data management problem, and I was hoping that you would
be able to help me.
I have a Stata data file containing about 60,000 names and addresses. The
addresses are held in 6 different variables, add1-add6, corresponding to
different lines of the address. The postcode can appear in any of the
address variables.
I also have a separate csv file that contains the postcode districts in
Great Britain (the section of postcode before the space, e.g. for the
postcode 'SK17 9JN' the postcode district is 'SK17'), and what county the
district belongs to (for example, the county for SK17 is "East Midlands").
There are about 2,800 postcode districts in total.
What I want to do is identify the county the individual lives in using the
postcode of their address. I thought that I might be able to do this as
follows:
For each line in the postcode csv file:
1. Identify if the postcode is present in any of the address variables
using -strpos(s1,s2)-
2. If present, set the county of the individual to be the county
corresponding to that postcode district from the csv file.
However, I am struggling to find a way to loop through the rows of the csv
file to enable me to search for each of the postcode districts in the
addresses.
I would greatly appreciate any help with this, as I am struggling to think
of a way to do it. Please let me know if anything needs clarifying.
Many thanks,
Gillian
