Pete,

I've been working on a few modifications to gamedemo.ex which you posted to
the list a couple of weeks ago.  The problem I've run into is loading a new
screen (that is, the good guy walked all the way across the first one...)
 I tried making the game_loop function re-entrant by adding these lines


    free_command(level_cmd)
    free_command(gamebar_cmd)  -- one I added.
    free_command(back_cmd)
     free_screen(back_buffer)


to the end of the procedure, and then reloading the level.  The main
routine looks like this:

------------------------------------------------------------------------
----
-----------------------------------MAIN---------------------------------
----

if gfx_mode(800,600,8) then
    FATALERROR("Your computer can't display 8-bit SVGA graphics")
end if

    load_data()                         -- just some precursory info
    init_sprites()                 -- just the good guy for now
    load_level("levels\\21.lev")
    load_gamebar()

while 1 do

    game_loop()
    load_level(level_name)
    load_gamebar()
end while

restore_mode()

When I execute the program, it works fine for a few screens, but then after
about 4 or 5 screens, it always generates a causeway error.  I was
wondering if you give me a few pointers on how to trap this nasty little
bug since you've probably had 1 or 2 yourself.

If you want to see the source code, I'll send by private e-mail as it's too
large for the list.

Thanks.
