But there is a command to do it. This crossed with my post pointing that out. It is -egen, concat()-. Or alternatively this is possible with basic functions: gen var12 = real(string(var1) + string(var2)) or gen var12 = string(var1) + string(var2) or gen var12 = real(var1 + var2) or gen var12 = var1 + var2 depending on what you have and what you want. (Your question did not specify whether you had numeric or string variables.) Nick n.j.cox@durham.ac.uk John Ataguba Thanks Johannes and Ashim. The suggestions were great. I thought there could be a command to just do this without going through manipulations.
