GET-statement with or without VIA option.

[Merol Newman]

I'm sure Bob is right - it was just something I wouldn't have trusted to work.

But looking at your Qshow list, I think TNUENDRMNT might be a temporary item. Does it get reset at
the right point? You could put an info statement just before the GET to test this. If not, it would
work OK when the value of TNUENDRMNT is the same as for the previous record.

Is the "while retrieving" loop in the same program? You might be calling the ghost screen from
another screen, and passing the temp from that - in which case if the temp is "reset at mode", it
will be re-initialized as the ghost screen is called - an obscure bug, but we've had it happen!

On the subject of GETs in initialize procedures, I've written several processes which do the same
sort of thing as you're doing - running Quick code against a file with a "while retrieving" loop.
I've always used INITIALIZE without problems, but I think you can use ENTRY in the same way. It
might be worth a try!

Good luck!
