Length of TStringField

Hi,

can anyone help me with a problem concerning TStringfield. I the Delphi
Help I can read, that a TStringField can have a length up to 8192
characters. When I define the length greater than 257 characters I get
the error message 'Invalid Fieldtype'.
This problem occurs with Delphi/Connect for SAP but I think it's a
Delphi problem.
I am using Delphi 3.02

Thanks for help
