random number for a column inside WITH loop for all records

can you just have a random number for a column for all records within a WITH loop?
      With ds
        .AddNew
<columns> values assigned
<Column5, for example should have the same random number for all the records updated within the WITH loop>
<In the next time the loop is run, all the Column5 column values should have the a random number, but all same just for that loop
etc>
        .Update
      End With

for example, in the first loop with the first flat file, there may be 3 records for example.For all 3 records, the 5th column should have the same random number.

example:
1,2,3,4,563843347
2,3,4,5,563843347
3,4,5,6,563843347

In the second loop, there may be 7 rows for example, but all of the 5th column should have the same random number together again.

11,12,13,14,270267623
22,33,44,55,270267623
33,44,55,66,270267623
1,11,21,31,270267623
2,22,33,44,270267623
3,4,5,6,270267623
9,0,9,0,270267623

how can this be done?

Thanks

Set a var to a random number just before entering the loop.  If this code is inside a method, for instance, every time the method is called, a new random number will be created before entering the loop the next time.  Assign the value in the var holding the random number to column 5.
