No special way of doing this springs to mind.
gen newvar = x1 if index == 1
forval i = 2/5 {
replace newvar = x`i' if index == `i'
}
or for those who were LISP programmers in
some previous phase
gen newvar = cond(index==1, x1,
cond(index==2, x2,
cond(index==3, x3,
cond(index==4, x4,
cond(index==5, x5, .)))))
