Hi Hilmar and Fabio.
I would, in a way, support Fabio in terms of bringing MS SQL SERVERness into VFP data types (field and variables). I, contrary to Fabio, deal with big numbers. To do maths on 15+ digit numbers you have to construct complex and poorly tested (we are talking big time money here) kludges.

Best wishes.
Kamil

I think you will also have a wider variety of data types in some languages (I am not sure exactly what you get in Delphi): types like 1, 2, 4 or 8-bit integers, BCD, floating-point that has a somewhat greater precision (more significant digits) than what is available in VFP.
