st: Combine two variables in a dataset

[<M.Sanchez-Sache@lse.ac.uk>]

Hi all
 
I'm trying to find the command two combine two variables in a dataset, but I couldn't find what I need. I check the -stack- and -stak- commands, but they don't perform the type of variable combination I need. 
 
I have two variables "division" and "model"
 
DIVISION                  MODEL
Acura                              TL
Acura                              TL
Acura                              NSX-T
Acura                              NSX-T
Acura                              RL
Acura                              CL
Acura                              CL
 
and I want to create one variable out of these two, say "car"
 
    CAR
Acura TL
Acura  TL
Acura  NSX-T
Acura  NSX-T
Acura  RL
Acura  CL
Acura  CL
 
I need to do that because I have another dataset with the variable "car" and I want to merge these two datasets.
 
Thanks!
 
Marta.
