       _d_._z_o_o_m allows the user to interactively adjust the settings of the cur-
       rent geographic region using a pointing device such as a  mouse.   Like
       _g_._r_e_g_i_o_n,  _d_._z_o_o_m  re-defines  the  settings  of the geographic region.
       However, _d_._z_o_o_m allows the user to change the current  region  settings
       interactively,  by  either  outlining  the  new region perimeter with a
       mouse, unzoom or pan the region.  The graphics display  is  updated  by
       the module.

       After  the  user  types	the  command  dd..zzoooomm  a mouse-button menu will
       appear directing the user.  Additionally the  region  settings  can  be
       modified by running _g_._r_e_g_i_o_n.  The user may also alter the current geo-
       graphic region by running the "region" option of the _d_._d_i_s_p_l_a_y program.

NNOOTTEESS
       Although  it is not necessary that the user display a map in the active
       display frame before running _d_._z_o_o_m, it is helpful to do this for  ref-
       erence.
