Appending the string result

Hi all, I have 4 infoobjects say name1,name2,name3 and name4, each having the lenght of 60 . Now In the bex query designer i want to add this 4 infoobject like

result = name1 + name2 + name3 + name4.

I think that can be achieved by using the formula variable, but i am not sure about it , Plz help me in solving this issue.
