RE: Empty subfile shows as filled

I usually use the erase keyword along with a message when I know the
subfile is empty. I've also seen people write "No records found"
messages in the first subfile record.
In the example below *IN38 is shutoff when the subfile is empty so the
subfile format is erased.

A 31 SFLCLR
A N31 38 SFLDSP
A N31 SFLDSPCTL
A N38 ERASE(V57832S)

Subject: Empty subfile shows as filled

Hi,

I have a subfile that shows customer transactions. To view cancelled
transactions, the user presses a function key and the subfile is cleared
and recharged with all the transactions. Pressing the function key again
recharges without the cancelled transactions.

Case : the customer has only one transaction that is cancelled.

The first time, the screen shows no records, so OK.

Press the function key, the screen shows the cancelled transaction.

Press the function key again, the screen continues to show the cancelled
transaction, despite the fact that the subfile is empty. I seem to be
viewing the screen underneath the last screen.

This problem does not show if I try to debug.

What can I do ?

Thanks
