>this abbreviated piece of code is the root of my problem. if a file has records in it, this works fine. but if i zap the file it won't work. in other words if the file is empty it wont work. it seems to be a problem with one particular file only. with other files i dont run in to the problem. any suggestions?

Where does it fail? Does the lock fail? Append Blank? Replace?
