SBROWS()

  Short:
  ------
  SBROWS() Determine number of rows in a box

  Returns:
  --------
  <nRows> => rows in the box

  Syntax:
  -------
  SBROWS(nTop,nBottom,[lIncludeFrame])

  Description:
  ------------
  The number of rows of a box with top of <nTop> and
  bottom of <nBottom> is returned. By default, the frame is
  included (the top and the bottom)

  [lIncludeFrame] by default is True - and all rows are
  counted. If passed as False, only the inside rows are counted.
