(FileEditorMdiSubWindow::initEditor): Change first argument to AbstractTerminalView* and store into m_terminalView. * src/MainWindow.h (AbstractTerminalView.h): New include, replacing TerminalView.h. (MainWindow::m_terminalView): Change member type to AbstractTerminalView*. (MainWindow::terminalView): Change return type to AbstractTerminalView*. * src/MainWindow.cpp (MainWindow::openEditorFile): Change first argument of FileEditorMdiSubWindow::initEditor call to AbstractTerminalView*.

## Display a dim-vector object.

define display-dims
  echo ndims: \ 
  output $arg0.rep[-1]
  echo \ndims: \ 
  output *$arg0.rep@$arg0.rep[-1]
  echo \n
  dont-repeat
end

document display-dims
Usage: display-dims DIM_VECTOR
Display the contents of an Octave dimension vector.
end

## Display a dense array object.

define display-dense-array
  echo array object: \ 
  output $arg0
  echo \ndimensions:\n
  display-dims $arg0.dimensions
  echo \nrep = \ 
  output *$arg0.rep
  echo \nrep.data = \ 
  output *$arg0.rep.data@$arg0.rep.len
  echo \n
  dont-repeat
end

document display-dense-array
Usage: display-dense-array ARRAY
Display the contents of an ordinary, i.e., dense Octave array.

See also [display-sparse-array] for showing the contents
of sparse Octave arrays.
end

############################################################
## Display a sparse array object.

define display-sparse-array
  echo sparse object: \ 
  output $arg0
  echo \ndimensions.rep[0] = \ 
  display-dims $arg0.dimensions
  echo \ndimensions.rep[1] = \ 
  output $arg0.dimensions.rep[1]
  echo \nrep = \ 
  output *$arg0.rep
  echo \nrep.d = \ 
  output *$arg0.rep.d@$arg0.rep.nzmx
  echo \nrep.r = \ 
  output *$arg0.rep.r@$arg0.rep.nzmx
  echo \nrep.c = \ 
  output *$arg0.rep.c@($arg0.rep.ncols+1)
  echo \n
  dont-repeat
end

document display-sparse-array
Usage: display-sparse-array SPARSE_ARRAY
Display the contents of a sparse Octave array.

See also [display-dense-array] for showing the contents
of ordinary Octave arrays.

## Display Octave debugging stack 

define show-octave-dbstack
  call show_octave_dbstack ()
end

document show-octave-dbstack
Usage: show-octave-dbstack
Display the contents of the current Octave debugging stack.

This is the function stack that the Octave interpreter is processing
and will be different from the C++ stack being debugged with gdb.
