I'm not exactly sure what you tried Garrett ...

I implied that it was not logical to lock a (new) buffered record, and since it didn't raise an error, it's actually anybody's guess as to what VFP actually does when you issue a command that normally only operates on "real" records vs "virtual" records (ie. "trying to lock").

>>Your APPENDed record is "in the buffer"; by definition, it is already exclusive to you and "invisible" to everyone else until you TABLEUPDATE, or move off the record.
>>
>>In the current context, you are not locking your appended record (in the buffer), you're trying to lock the "current record" in the table ...
