Replace value while keeping original label

[Jay Rege]

Hi everyone,

I would like to replace the value of X1 (SN1) by X2 (SN2) while keeping the original value label of X1 (SN1).
For example:

* Example generated by -dataex-. To install: ssc install dataex
clear
input long SN1 float SN2
  1   1
  1   1
 61 121
129  10
 83 490
end
label values SN1 SN1
label def 
SN1
 1 "__NA__", modify
label def 
SN1
 61 "Frank Steinmeier", modify
label def 
SN1
 83 "Helene Fischer", modify
label def 
SN1
 129 "Merz", modify

here I would like to : replace SN1 = 121 if SN1 == 61 while keeping the label "Frank Steinmeier". Ultimately I would like to do it for all values automatically. Replacing SN1 by SN2 while keeping the value labels of SN1.

Many Thank for all ideas.

Best, Jay

You don't have to replace the values of SN1 with the values of SN2, you can simply copy the value labels of SN1 to SN2 like this.

labmask SN2, values(SN1) decode

labmask is community-contributed software, either from SJ or SSC (as part of the labutil package). I agree that this is the most convincing tool here.
