_EXTRA is the way to go, but as a side note, you wouldn't have needed a long
list of case statements but just a single call to OPENU with all the
keywords present. OPENU will consider the keywords set only if they are
present *and* have a non-zero value. So if they weren't defined in the
call to the wrapper procedure, they won't be considered set by
ENU. --Wayne
