embedded SQL: group by rollup()

[Booth Martin <booth@xxxxxxxxxxxx>]

LOC can be "L1" "L2" or "L3"

This compiles:
         exec sql Select LOC,
           SUM(COALESCE(Sum(ORD), 0)) into :wORD
           from FILEA
           where ITM = :wITM
           group by rollup(LOC)
           order by LOC

but now what? How do I get the rolled up totals for L1.wORD, L2.wORD, 
and L3.ORD?
