Dear statalisters

I have a data file with 2 variables and duplicates on one of these 
like:

id  var1

1    3
1    4
1    5
2    2
3    2
4    5

Now I want to turn each id into one unique record, and turning the
information on var 1 into a range of new variables so that 
I would like to end up with a data file looking like: 

id var1 var2 var 3
1  3     4     5 
2  2     .     .
3  2     .     .
4  5     .     .

Does anyone knows if it is possible?

Regards
B. Hansen
