I have groups of variables contactoutcome_con_<y>_<x> and contactmethod_con_<y>_<x>, where x is a program from 1-8 and where y indexes the contact attempt (goes from 1-30) associated with that program. For example, contactoutcome_con_30_8 is the outcome of the 30th contact attempt made by the 8th program, and contactmethod_con_30_8 is the contact method that was used for that attempt. I need to generate a new variable "contact_success" based on the values of these two variable. For example, contact_success should = 0 if contactoutcome_con_<y>_<x>==9 AND contactmethod_con_<y>_<x>==11. What is the shortcut for doing this for all the 240 matching contactoutcome_con_<y>_<x> and contactmethod_con_<y>_<x> pairs? Thanks in advance!
