_D_e_s_c_r_i_p_t_i_o_n:

     This function can be used to control (for the current device)
     whether the user is prompted before starting a new page of output.

_U_s_a_g_e:

     devAskNewPage(ask = NULL)

_A_r_g_u_m_e_n_t_s:

     ask: 'NULL' or a logical value.  If 'TRUE', the user is prompted
          before a new page of output is started. 

_D_e_t_a_i_l_s:

     If the current device is the null device, this will open a
     graphics device.

     The default argument just returns the current setting and does not
     change it.

     The default value when a device is opened is taken from the
     setting of 'options("device.ask.default")'.

     The precise circumstances when the user will be asked to confirm a
     new page depend on the graphics subsystem.  Obviously this needs
     to be an interactive session.  In addition 'recording' needs to be
     in operation, so only when the display list is enabled (see
     'dev.control') which it usually is only on a screen device.

_V_a_l_u_e:

     The current prompt setting _before_ any new setting is applied.

_S_e_e _A_l_s_o:

     'plot.new', 'grid.newpage'
