Dear Statalist users,

I want to generate a new variable
Vnew= V2, but using V2x or V2y will depend on the value of V1

Vnew =V2x if V1=x
Vnew =V2y if V1=y

ID	V1	V2x	V2y	Vnew
1	x	6	12	6
2	x	7	13	7
3	x	8	14	8
4	y	9	15	15
5	y	10	16	16
6	y	11	17	17

What is the command I should use if I want the result of Vnew look
like the above table?
Thanks

Betty
