I ignored this case:

Let me try again.
select distinct(cast(trim(
case when mychar = ' ' then '0' else mychar end
) as integer))
from qtemp.jhhl
order by 1;
Returns: 0, 73, 120

That worked with your test file, but failed when I applied it to the real thing . . . then I remembered that this thing had been populated from a spreadsheet . . . WITH the column headings. So when I change the
. . . = ' ' . . .
to
. . . < '0' . . .
it produced exactly the desired result. Thanks!
