Very easily -- by using dictionary or alphanumeric order. Otherwise you
could not ever -sort- a string variable. 

di ("3" > "2") 

will display 1 (for true). It is also true that ("10" > "2") is false.
Whether this is what Daniel wants I don't know. 

Hence I can't advise: except that >= sounds nearer the mark than >.

Well, how is Stata supposed to figure out whether string "2" is greater
than
string "3"? Numbers in the format of string have no natural order. Just
-destring- them.

I have a question about list command; this is what I'm doing:

list ndc old_ndc e49_ gpi g64_ if gpi>"2"

gpi is a str variable (it is a 14 digit code) & I know is wrong but I
can
not figure it out how I can ask the program give me all ndc that has 2
or
more gpi.Thanks
