           geoLIGHTNING 2.1

      by Brian L. Crosthwaite


 [NOTE:] geoLightning was written in
goBASIC, which needs to have the GEOS
Optimised Mode turned off from the
Toolbox within Wheels to get it to
work.


  In the tradition of my infamous
screen burners, comes geoLightning 2.1
L. geoLightning is simply a fun
program to mess around with. It is a
small mathematical ditty that renders
lightning strikes onto the screen of
your computer. Here's the Bird's Eye
Lowdown....

 [GEOS]
 [----]

  [INFO]
  [----]

 Simply, that, a bit of useless info,
kinda gratuitous, but it's there none
the less ;)


 [FILE]
 [----]

  [HOT KEYS]
  [--- ----]

 Calls up a dialog box that lists keys
that can help you along.

   When you select view mode (below)
you continue by pressing [RETURN].

   [UP ARROW] will exit plot mode, so
when you've selected 20 strikes and
told your machine to render, but
sanity sets in once again, you can
abort this madness at any time.

   [STOP] will drop you directly back
to the Desktop as if you had never run
the fool thing in the first place!
Well, ok it won't erase any pictures
you saved or anything thing like that,
but it'll get you out at just about
any point within the program.


  [VIEW]
  [----]

 Loads the last completely rendered
picture for your viewing pleasure.
[RETURN] brings back the menu.


  [SAVE]
  [----]

 Opens a requester that lets you type
in a name to save a picture under.
Unfortunately there is no directory
listing, so don't use an existing
filename or you'll be dumped to the
Desktop and your picture (unless
completely rendered) will be gone.
Also make sure before hand that there
is enough room on the disk prior to
running. This is what I consider to be
the week part of the program as you
may have something totally awesome to
save, but stopped the rendering to
save it -- then running out of room on
the disk -- I think you get the idea.


  [LOAD]
  [----]

 This will open a requester asking for
the name of a file to load -- no
directory available here either, but
since it erases what's on screen
anyway, you can exit look at the DIR
then reload.


  [PRINT]
  [-----]

 Will print out your wonderful new
creation. Beware it will print a black
page with white strikes on it at full
page (over half a sheet) -- you might
want to use this sparingly.


  [QUIT]
  [----]

 I don't know what this does.


 [PLOT]
 [----]

  [lightning!]
  [----------]

 This is kinda redundant on this
version, there was another option
called mask on the C128, Amiga and
Atari ST versions of the program, but
selecting lightning will begin the
rendering process. It takes a while,
but is a zillion (a highly technical
term) times faster than version 1.0,
or Zx.

 A note about the SuperCPU: the math
is made to work under the regime of
the 8602 (I haven't tested it on an
actual C64 as my 64 is not set up for
GEOS, only my 128D and it works in
both GEOS2.0 and GEOS128 2.0. Sorry,
I've been told it does not work under
Wheels :(

 Any who, the math makes strange lines
on the screen that tend to go more to
the left of the screen most of the
time with the SuperCPU -- I do hope to
tweak it into submission when next I
get a chance, mean while you'll just
have to settle for the fast plot mode
(still, below).


  [STRIKES]
  [-------]

 Lets you pick how many lightning
strikes will hit -- choices are 1, 2,
3, 5, 7, 10, and 20. You can also add
to the ones already there (as long as
you complete the render, in other
words, not hitting [UP ARROW] before
the plotting session ends using the
keep screen option under the control
menu (yet, below).


 [CONTROL]
 [-------]

  [KEEP SCREEN]
  [---- ------]

 Opens a requester and asks if you
want to plot on top of (add to) the
last completed rendering phase.


  [RESET VARIABLES]
  [----- ---------]

 Sets everything back to the way it
was when the program was first run.
This will not turn off fast plot
mode.


  [THUNDER BOLT]
  [------- ----]

 Opens a requester asking if you want
to have the computer make that cheesy
sound at the end of every strike,
rather than wait until they are all
rendered.


  [LIGHTNING FLASH]
  [--------- -----]

 Opens a requester asking if you want
to flash the screen upon completion of
each strike.


  [FAST PLOT]
  [---- ----]

 Opens a requester asking if you want
to use the fast plot. The fast plot
simply plots half the dots over double
the screen (what? -- cuts screen in
half, calculates half the plots and
plots two dots at 2 time the y
coordinate to fill the screen more
quickly).


 [NOTES]
 [-----]

 There must be a bug somewhere as I

ust had thunder bolt and lightning
flash selected and when it finished it
popped me back to the desktop. :/
Darn. Well, guess I'll be working
sooner than I thought.

 Enjoy the program, but don't take it
too seriously as it is meant as a
diversion more than anything else.
