hi,
thank you very much,
it works as Mr.Tamar(message).

delete WorkTable;
       from WorkTable;               
inner join RecToDelete on WorkTable.telNo = RecToDelete.TelNo

>VFP9 Help at http://msdn2.microsoft.com/en-us/library/6kt4x6zx(VS.80).aspx doesn't give an example of INNER JOIN in Delete and thus I could not figure out the correct syntax. I don't remember if I tried it in VFP9 before myself.
