Not even close. You're checking for presence of string 'thh05' in the table name (including path). And comparing result of comparison with .F. is totally unnecessary. That what NOT is for

SELECT 0
USE (cFile) 
IF TYPE(ALIAS() + '.' + thh05) <> "U" 
  USE
  Alter Table c:\db\past.DBF Rename Column thh05 To thh11
ENDIF
USE
