They contain observations like (1, "one"), (2, "two"), (3, "three"), etc. Now I would like to write a specific value into a local macro. For example, I might be looking for the text that goes with the observation with number==2, and would like to assign that value to a local macro. Very amateurishly, I was looking for code similar to the following:

If your dataset _really_ is as you described you can
. sort number
. local v = text[2]
With _really_ I mean: number contains only
(a) positive integer numbers
(b) each number exist only once
(c) no gaps in between two subsequent integer numbers
(d) no missings
Otherwise the above will fail.
