Hello Nils,
OK, then something doesn't work.
When I try your suggestion, I get this:
[EMAIL PROTECTED] mclient -d demo -l mal
mal>b := bat.new(:int,:int);
mal>io.print(b);
#-----------------#
# h t # name
# int int # type
#-----------------#
mal>bat.setName(b,"test");
mal>bat.setPersistent(b,true);
mal>transaction.commit();
mal>\q
[EMAIL PROTECTED] mclient -d demo -l mal
mal>b:= bbp.bind("test");
mal>io.print(b);
MAPI = [EMAIL PROTECTED]:50001
QUERY = io.print(b);
ERROR = !TypeException:user.main[1]:'b' may not be used before being initialized
mal>\q
I have downloaded and compiled MonetDB-Mars-SuperBall-SR3.tar.bz2 on an Ubuntu
i686 single cpu system running a 2.6.20 kernel.

I already tried 'mclient -l sql' without any apparent problems, so it appeared
unlikely that there were bigger issues.
I will try to run the test suite(s).
Thank you very much

okay here a small example then
b := bat.new(:int,:int);
io.print(b);
bat.setName(b,"test");
bat.setPersistent(b,true);
transaction.commit();
# after server restart the following should work.
b:= bbp.bind("test");
io.print(b);
