exec sql end declare section;
tot_hours = 0; overhours= 0;
exec frs unloadtable emptasks tasktable(:hours:ni=hours,
:state=_STATE);
exec frs begin;
if (state != 4 && state !=0
&& ni != -1)
tot_hours = tot_hours + hours;
exec frs end;
tot_cost = tot_hours * hourly_rate;
exec frs putform emptasks
(tot_hours=:tot_hours,tot_cost=:tot_cost);
if (tot_hours 40)
