_n is 1 as default, so your "testmacro" thing gets stuck in position
"Andrews ". Note that _n refers to a position in the dataset, which you do
not change in the loop...

Subject: st: Looping with label define
Hello:
I am trying to define labels for a numeric variable (countynumber) using
an existing string variable (county) so that the the countynumber will
take on a value label equal to the county for that same row.
I would like to use looping with the "label define" command to complete
this task.
(I've been successful with using looping with the encode and replace
commands to get this to work (after sorting the data), but my dataset has
many variables (sorted in several different ways) that will get the same
set of value labels & minor tweaks to the these value labels may occur
frequently and so I'd like to be able to make those changes to one column
and then apply it to all the associated variables in my dataset)
An example of what I've tried is below. When I run this code, it applies
"Andrews" as the value label for all of the values in countynumber.

input str20 county countynumber
Andrews 1
Anderson 2
Austin 3
Bexar 5 Childress 4
Denton 6
end
local testmacro = county[_n]
forvalues num = 1/6 {
label define lab `num' "`testmacro'", modify
}
label val countynumber lab

Thanks for any help!
