The frammitz just zilched!

                if (frammitz_status 0)
                {
                dbg_printf ('Error: Frammitz status: %d.\nProgram terminated',
                frammitz_status);
                signal ('42666', 'Frammitz zilched');
                }

Hitting these lines would cause something like this in a client:

*** Error 42666: [Virtuoso Driver][Virtuoso Server]Frammitz zilched at line 84 (84) of Top-Level:
                zappi()

The console output would look like this:

Error: Frammitz status: 2.
                Program terminated
