Subject: Just noting syntax change...

Here are a couple lines:

      seconds = str2num(rin);
      if (seconds ~= [])

 that I think used to work equivalent to:

      seconds = str2num(rin);
      if (~isempty(seconds))

However, the test:

      seconds ~= []

now produces

      ans = [](0x0)

that is,

octave:21> seconds = str2num("4.55")
seconds = 4.5500
octave:22> seconds ~= []
ans = [](0x0)

I'm changing over to "isempty" under the assumption that "seconds ~= []" 
is no longer valid syntax.
