>I'm using a VB program but accessing the tables thru VFP. If I put a checkbox on the form and set the value to 1 or T, a T overwrites the 'Y' in the table. I need to convert the table (or field value) back to a 'Y' so the 3rd party program will recognize it.

After you made changes to that misterious table in your VB/VFP program you can open mytable.dbf with low-level functions and change T to Y.
