#c0 := b.select([EMAIL PROTECTED], oid(b.count() - 3)).mark([EMAIL
PROTECTED]).reverse();
cnt := aggr.count(alg);
cnt := calc.-(cnt,3);
id := calc.oid(cnt);
sel := algebra.select(b, [EMAIL PROTECTED], id);
mrk := algebra.markT(sel, [EMAIL PROTECTED]);
c0 := bat.reverse(mrk);
I did like this and I still get:
[EMAIL PROTECTED] MonetDB5]$ ../../bin/mserver5

!TypeException:user.str2qgrams[26]:'algebra.select' undefined in:
sel:any := algebra.select(b:bat[:str,:void], _27:oid, id:oid)

So for all the functions inside [<func>] I should use
batcalc.<func> , right?
