Re: st: Fwd: how to use the label of oldvar to name newvar

I have tried to egen, group option with the label, and that ends up
with the same problem as when I just use the encode option.

My data looks like this

atc
"aaabbc01"
"aaabcc02"
"aaabbc04"
"bbbcdd01"
etc (40 different total)

When I use encode atc, gen(n_atc) it becomes
n_atc
1        with value label "aaabbc01"
2        with value label "aaabcc02"
3        with value label "aaabbc04"
etc

Then I have used gen atc_`xx' = 1 if n_atc==`xx'                //xx
being the values of n_atc (1-40)
But instead of atc_xx I would like my 40 new variables to be named
after the original string values e.g. the first var will then be named
"aaabbc01"

hope you can help me :)
