Hi, I know this may seem simple but I just can't figure it out.

I have 3 variables: Time, serial, code

Time expresses years, serial is a identifier variable and code is a variable which ranges between 1 and 50.

I want to generate a new variable (lets call it "nv") which contains the values of this 3 variables in this order: Time|serial|code

So for example if I have the following:

Time: 1999
serial: 143
code: 4

My new variable should look like this:

nv: 19991434



Thanks for your help.
