I'm new at Visual Foxpro programming, and my collegues warn me of using the grid directly as a data entry form - saying something about buffering of tables that mess-up my data. How true is this?

Is there any way to go around the problem but still use the grid for data entry? Because it would be awkward for users to enter information on another window and only have the grid reflect what was entered, especially when entering order slips, delivery receipts, invoices, etc.

Are there any reading materials that can help explain how to manipulate the grid better?

Thanks in advance for any help offered.
