No, I mean to say that if SET NEAR is ON then any logic that expected EOF() to indicate whether or not a record was found will fail because EOF() will not go true when no record is found. EOF() being .T. is not an indicator of seek failure when SET NEAR is ON.

The real problem is that you may have code that uses IF EOF() to indicate that the SEEK failed and then that code may7 get called from someoneelse's code that SETs NEAR ON without you knowing it, oops.

EOF() tells you whether or not the record pointer is at EOF() and FOUND() tells whether or not a seek or locate succeeded. Use the function that is designed for the job you are asking it to do.
