Help text

 function frame ( arg1, arg2 ) ;

 script to define the rectangular graphics window boundaries.
 it also defines the global variable FRAME

 ******************************************************************
  It is important to call make sure FRAME is set right
  before using DRAWCOASTS, CY_CONTOUR and SET_ASPECT.
  This routine uses the global variable FRAME to set parameters
 ******************************************************************

 If call without any argument, it would revert to the frame defined
   by the last call to it; if call the first time without argument,
   frame will be set to [ 0 360 -90 90 ];
