What is SQLdatasource parameter 'size'?

Hi,
I'm new to ASP.NET 2.0 and I am trying to get more information on the
size property within the parameter tag of the SQLdatasource control.
I have this code as an example...
<asp:Parameter Type="String" Name="NewID" Direction="Output" Size="4">
Does Size="4" represent 4 characters in length? In the case of an
IDENTITY integer being returned after an INSERT, does having size = "4"
mean that the integer can be up to 9999?
What does the number represent?!
Thanks in advance,
John.

For a string it's the size in characters. Your example corresponds to a
"char(4)" (or "varchar(4)", "nchar(4)" or "nvarchar(4)") in SqlServer.
I don't think the size is be needed for integers, but then it would be
the size in bytes, not the number of digits in the decimal
representation of the value.
