I seem to recall a similar line of code where I could something like
sele stocktable
delete for (select sum(qty) as ttl, stockcode from othertable)
I was hoping to do this in 1 line, but as Tracy said, maybe a scan will
have to suffice
scan
select SUM(qty) as ttl,stockcode FROM invtable where
stockcode=stocktable.code
if ttl=0
sele stocktable
delete
endif
endscan
