Rename all variable with their label values

Question

I would like to rename all variables in my Stata dataset with their label values automatically.

Any idea of how this can be done?

Example data:

input str13 usa str9 v338 str13(fra gbr)
"1.443888e+05"  "0" "7.402382e+04"  "2.017132e+05"
"1.540046e+05"  "0" "2.091502e+05"  "1.863581e+05"
"1.339439e+05"  "0" "1.898640e+04"  "1.540931e+05"
"1.340120e+05"  "0" "6.982494e+04"  "1.554574e+05"
"1.339604e+05"  "0" "5.265134e+04"  "1.593273e+05"
"1.436713e+05"  "0" "2.477454e+05"  "2.010521e+05"
"1.339533e+05"  "0" "2.244940e+04"  "1.542236e+05"
"1.339438e+05"  "0" "1.898623e+04"  "1.540923e+05"
"3.089005e+05"  "0" "2.489533e+05"  "1.941806e+05"
"1.387412e+05"  "0" "2.759644e+04"  "1.538440e+05"

EDIT:

Do you know a way to start from the second occurrence of local macro countries? I would like to exclude the first column from the local macro list.

end 

label variable usa USA
label variable v338 Unknown1
label variable fra France
label variable gbr Britain

ds
local countries `r(varlist)'

foreach var of local countries {
    rename `var' `: variable label `var''
}

I used some toy labels for the example and the command ds to obtain all the names of the variables in the dataset in a local macro.

EDIT:

Type ds usa, not instead of ds.

Rename all variable with their label values
