>How does Delphi help your data moves faster? Maybe your GRIDS are slow
>because the data is on a network drive?

True, the data is on the network drive. However, I have tried the app with the data on a local drive, and my VFP app is not any faster. At any given time there is not much more than 500 records selected in the view on average. So the data comes into the view almost instantly. My problem is scrolling speed. If you have followed Drew Speedie's notes on 'Tricks with Grids' you will know that there is a major reduction in speed if you put any code in the After/Before RowColumnChange Events. When you hold down the down arrow key for about two seconds, VFP scrolls the grid at a reasonable speed. However, if you have other objects on the form which you want refreshed as this is going on, don't hold your breath. If you hit the down arrow key intermitantly, performance is real sticky but other controls on the form do refresh.

What like syntax does Delphi use?

I'm not too clear on this question. But if you are referring to macro substitution to build the SQL statement dynamically from which to populate the grid, you can be very sure that there is similar functionality in Delphi 2. The trick is to load a string and call a function that evaluates the string at run-time.

If you are referring to object notation, Delphi 2 is quite similar to VFP. However the language is OOP Turbo Pascal 7.

Not yet, but in a months time, I will make a posting. I'm too busy with this VFP project at this time. But you can look at the May 97 issue of BYTE magazine for a review of Delphi 3.0
