TO SET COMPUTATIONS

$ Correction of the elevation (refraction):$
  This option active or unactive the |precis| computing
  of the elevation of planets.
  When this option is |active|, the parameters for 
  refraction computing are :|temperature|, |atmospheric
  pressure|, |form of the earth| (it is not a sphere)
  The default algorythm used is the @simplest and faster @
  The others are more elaborated and more or less precise
  with the elevation on the sky.
  
  Refraction on the horizon is:
      |Nautic ephemeris|: 33.8'-10 degrees-1013 mB
      |Ephemeris of Bureau des longitudes|: 36.6'-0-1000
      |Astronomical almanac|: 34.0'-10-1010
 
 You can active or unactive |precis computing|
 A non precis computing use extrapolated SIN and COS and
 it is 10 x faster.
 If precise computing is not actived, conjonction and
 opposition calculations are |one hour| precise, otherwise
 they are |one minute| precise.
 The |Earthly Dynamic Time| (E.D.T) take earth slowing down
 into account .(Several hours on 2000 yars)
 
~
TO SET TIME

 With this menu you can modify the Time Zone of your 
 observation post.
 |Universal Time|: It is the astronomical time and all the

 In $FRANCE$, there is a |winter time| (+1h) or a |summer|
    time (+2h)
 In other case, you can choose between |U.T| and |local time|
 
 @Cities of FRANCE are in the FRANCE.VIL file @
 If you live in $LA REUNION$ or in $WEST INDIES$ , you can
 choose these places with options.

   Alphanumeric keys (1-8) active these times.
   
  
* User can modify the scale: By clicking on the vertical scale
  you can choose the number of graduations and value of the
  start and the end  of the scale.
* Automatic setting of the scale is done by CONT key and a
  click on the planet symbol.
* The symbol option allow to draw the symbol of the planet.
* Each curve may be setting for 
          - colors (16-256 colors)
          - line type
          - frame type 
          - curves type ( histo, circle, line,..) 
          - back of the window is black or white, texts are black
            and white or color.
 To modify lines, frames, colors you must click on the rectangles
 under the symbols.
 By clicking on the right of the symbols, you can modify the line 
 type of the curves.

 To modify the date of start and the date of end you must click
 on the  2 buttons showing dates

You can change :
     * The number of compute steps ( 600 max )
     * the period for compute
     * The precis computting mode with the ALPHA button

 You can save curves with ASCII or graphic format or curves
 format ( with active parameters and computes).
 In addition, you can save screen 
 These files have an *.CRB code.

 You can print the ASCII variations.
 
 When you move the mouse index on the curve , datas are display
 on the right of the menu.

 Clicking near a curve display the planet card 

 Some objects are active or unactive as a function of the 
 curve selection.

 If the compute of the curve is not finish, you relaunch 
 computting with the ALT key and a click on the symbol
 of the planet.

    |Arrows| To select the next or the previous recapitulate
    board. If a planet is displayed, you have the next or 
    previous planet. If a comet ( asteroid) is displayed
     you have the next or the previous comet (or asteroid)
  Comets and asteroids are called with the @ see card @ option
  |SAVE|: To save datas in ASCII format
