In VFP, "bound" simply means you attach the property .ControlSource to a field. This is the easiest way to go, and should usually cause no trouble.

"Unbound" (ThisForm.Text1.ControlSource = "") would require you to write code, to copy values, e.g., from Table.Field1 to ThisForm.Text1.Value and back. Usually, this would not be required, so use the simpler alternative of "Bound" data.

BTW, I believe the terms "bound" and "unbound" are more common in other languages, like VB. These terms are not common in VFP.
