Dear All,

I would like to know if it is possible to read and save a particular
value in a dta file to macro. I mean one particular value of a
variable rather than the "variable itself".
I have a dataset of 2 columns and ten rows. One column has the
column_name of X which has a value of 1 to 10. The first row is 1, the
second is 2,.....
And I have another column which has a column_name of STR which is made
up of string, the first row is "a", the second is "b",.....

Can I pinpoint one particular cell in this dataset and save the
contents of this particular cell to a macro?
eg I want to ask STATA to give me the value of STR  when X=2, the
value should be "b".

local temp = STR if X==2 (of course, it does not work and that's why I
ask for help.)

Thank you very much for your help and have a nice day.
Allen
