This is a job for -reshape-, see -help reshape- and the example below:
*-------- begin example ------------
drop _all
input id var1
1 3
1 4
1 5
2 2
3 2
4 5
end
bys id : gen t = _n
reshape wide var1, i(id) j(t)
list
*--------- end example --------------
(For more on how to use examples I sent to the Statalist, see

Hope this helps,
