You're partially right, this code used to work in Octave 4.2, but not in
Octave 4.4. The break statement should only be used inside of a loop.

You may way to use something like this

    if (A == 0)
      disp ('Error: 1')
      return
    endif

or this

    if (A == 0)
      error ('Error: 1')
    endif
