Library /sys$common/syshlp/basichelp.hlb Graphics, SET Statements, ...ECHO AREA  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  The SET...ECHO AREA  statements  specify  the  boundaries  (in  device
  coordinates) of the echo area for the specified input type.

  Example

  OPTION TYPE = EXPLICIT
  DECLARE SINGLE left_1,right_1,bottom,top,input_value
  OPEN "office-term" FOR GRAPHICS AS DEVICE #1
  ASK VALUE ECHO AREA #1 : left_1,right_1,bottom,top
  !Set the echo area to the top corner of the default area
  SET VALUE ECHO AREA #1 : left_1 + (right_1-left_1)/2               &
                                   ,right_1                          &
                                   ,bottom + (top-bottom)/2          &
                                   ,top
   LOCATE VALUE #1 : input_value
