Hi!

I have been debugging a problem with Oldval(). On a newly appended record in a row buffered view, that has not been committed yet, when applying OldVal() (in program code) to numeric field that has had a value entered by the user, OldVal() returns .NULL.

Is this correct? OldVal() helps mentions nothing about this and specifies that the function returns a value commensurate with the column's data type.

If I go to the command window and browse the view, OldVal() returns the present value of the field but I assume that browsing the view committed the record hence the old value equals the current value.

Any insight on this will be appreciated.

Many thanks!
