st: Sort values in rows

["Nikolaos A. Patsopoulos" <npatsop@cc.uoi.gr>]

Hi all,

I have a large dataset with 5 variables that contains number in random 
order:
v1 v2 v3 v4 v5
28    1    25    22    14
23    2    3    34    39
6    16    8    24    19
3    45    8    1    37
4    23    27    33    10
16    41    33    13    21
...................................
................................



I want to sort them in such a way that the v1[i]<v2[i]<v3[i]<v4[i]<v5[i] 
for each i:

1 14 22 25 28
2 3 23 34 39
......
......
..


Any ideas?

Thanks in advance,

Nikos
