Stored Procedure missing result column names

All,

When calling a newly created stored procedure, I'm missing column names in
the returned cursor...

I see column names here:
declare C1 INSENSITIVE CURSOR WITH RETURN FOR
select
iitnbr as item_number
, idescr as item_description
from ioritemmst
where iitnbr = wItemNbr;

But with this, the item_description and line_nbr column names are blank!

declare C1 INSENSITIVE CURSOR WITH RETURN FOR
select
2 as line_nbr
, iitnbr as item_number
, idescr concat ',' concat idsize as item_description
from ioritemmst
where iitnbr = wItemNbr;

I've got older stored procedures that assign new names to that return
column names just fine...they were created on 7.1 but at an earlier PTF
level.

Still on 7.1, but running TR9..

Anybody seen else seen this?
