      JUMP.EXE is a program that lets you visually choose a planetary target
point, then calculates the edge-of-ship-screen way point for that jump.  
Simply unzip JUMP.ZIP in the same directory as your planets.exe file.  A sub-
directory named FONTS will be created and a FORTRAN font file will copied 
into it.  

      When you run JUMP, you are prompted for your ship's starting position,
either x-y coordinates or planet ID number.  Then, a portion of the Vga-
planets map, with your staring point at the center, is displayed on the 
screen.  A green circle 350 light years in diameter is drawn.  This allows you 
to visually see which planets are closest to the after-jump postion of your
ship.  Then, enter the ID number of the planet you have choosen and the x-y
coordinates at the edge of the ship screen are calculated along with the 
distance between end of jump point and the planet.

      At this point, another starting point for a different ship can be 
entered or press <Enter> to quit.  Pressing <Enter> at any prompt will exit 
the program.

      This can be done in reverse also.  Suppose a probe ship shows up on 
your scanners.  Simply enter the ship's x-y coordinates and trace the ship 
back to it's most likely staring point.

      JUMP.EXE requires VGA 16 color monitor or better (if you are already
playing Vga-planets on your computer, this should not be a problem, right?).
JUMP.EXE is a freeware program.  I take no responsibility for any problems
that may arise.  If you want the source code, let me know and I will get it
to you (JUMP.EXE was written in Microsoft FORTRAN 5.1).  Enjoy!
