i posted another message, and took some suggestions. after i'd changed my code
a bit, i compiled it. it had one error about argument 1 of blit having an
incorrect pointer type, but ignored it and compiled the .exe. then, after i ran
the program i got this weird error:
Shutting down Allegro

i don't know what went wrong. heres my code:

#include <allegro.h>

#define selecto 4

main()
{
RGB *pal;
DATAFILE *data;


allegro_init();
install_keyboard();
install_timer();

data = load_datafile("bmps.dat");

set_gfx_mode(GFX_AUTODETECT, 320, 200, 0, 0);

blit("bmps[selecto].dat", screen, 0, 0, 0, 0, 320, 200);

readkey();


return 0;
}

now, can somebody help me with this problem? also, are there any good
tutorials, documents, or anything that would help me with graphics for allegro?
