Re: white tunnel in a case structure at every output

[Al S]

A white tunnel on an output of a case structure indicates that the
tunnel is unwired in at least one case.  If you're using LabView 6.1
or 7, one option is to right-click on the tunnel and select Use
Default If Unwired.  But I prefer to wire to the output tunnels in
every case: it removes any question about what value is presented to
the case outputs.
