Hi Kenneth,

There is a difference
Theoretical but only theoretical there is a change that you keep in the Alt2
example 32 bits some time longer in memory. (Practical it would probably not
because it will be done by the garbadge collector in the same time). (The
last value stays also).

When you had done alt2 like this it had been the same

For Each tblRow As DataRow In Ds.Tables("tbl").Rows
Dim nCoValueAs System.Single
nCoValue = CSng(tblRow.Item("nCoValue"))

'Do something with nCoValue

Next

I hope this helps?
