Subject:      Lost Card Question (please see this one)
Content-Type: text/plain; charset="us-ascii"

Hi there,

After running the code below, there was no problem for step 3, but I got the
lost card information from step 4.
I feel strange about this:
I assume in step 3 SAS entered into the do until block twice,
which in effect is similar as the step 4,
thus we should have got the lost card information from step 3 as well,
but we actually do not get this information.

Could anyone please say anything about this? Thank you very much.

Best regards, Max
