>This is probably a very basic question with an obvious solution. I have a form that collects both character and numeric input. The data is saved to a table without trouble. The user sometimes needs to correct data already entered into the table.

Imo, you should just bind these controls to the fields. Then, you set the record pointer to the field you want to edit, or append blank and edit that record. Cleaner and your not trying to do what VFP already does for you with binding and buffering.
