I am refactoring old code (written in VFP 5) that check if user entry is unique in a table.

The table has NO index tags and it is a fairly small table (up to 100 records). The table is opened with Buffering 5.

My code is quire complex. Here is a summary of what it does:

1. Open the same table AGAIN
2. SET FILTER TO THE RECNO() <> nCurrenRecno
3. LOCATE FOR New User Entry.
4. If not found, the entry is unique.

Is there a simpler method to do it in VFP 9 SP1? Without, maybe, opening the table again?

Thank you.
