Betreff: st: dropping digits from variables in Stata 10
Dear All,
I am rather new to Stata so I apologize in advance if these are rather
silly questions, but I googled around extensively and searched Stata
help and cannot find an adequate solution.
1) I have got a variable consisting of 7 digit zipcodes. I want to
create a second variable which will only consist of the first 3 digits
of each zip-code and I cannot find a way to do it.
2) Some of the zipcodes start with 00, e.g 0037845 and Stata drops the
front 00 turning such zipcodes into 5-digit numbers (e.g. 37845). I need
to make Stata understand that these 00 are meaningful and return them
back into the zipcodes and I cannot find how to do this. They were
present in my original csv file, but when I converted it into a Stata
file using Stattransfer they were gone.
I will be most grateful for any help or advice,
Sincerely yours,
Ekaterina
