e. e. cummings fan?

This is how I got started with

1. After you've made Hello World with DJGPP (read
the FAQs and docs), try getting Allegro from
http://www.talula.demon.co.uk/allegro/
and installing it.
2. Rewrite your hello to use the Allegro library in the
VGA graphics mode; then try other graphics primitives.
3. Draw a bitmap in M$ Paint or whatever paint program you're
comfortable with; then save it as a 256 color bitmap and load it
in with this code. Once you have it working, play around with it:

/* readbmp.c */

#include <stdio.h>
#include <stdlib.h>
#include <allegro.h>

int main(void)
{
  PALETTE pal;
  BITMAP *bmp;

  allegro_init();
  install_keyboard();

  if(set_gfx_mode(GFX_AUTODETECT, 320, 200, 0, 0) < 0)
  {
    puts("couldn't set 320x200 graphics on this card; are you using a VGA or
better?");
    return 1;
  }
  bmp = load_bitmap("foo.bmp", pal);
  if(bmp != NULL)
  {
    set_palette(pal);
    blit(bmp, screen, 0, 0, 0, 0, bmp->w, bmp->h);
    destroy_bitmap(bmp);
  }
  else
  {
    textout(screen, font, "couldn't find foo.bmp", 0, 0, 15);
  }
  readkey();

  allegro_exit();
  return 0;
}

/* end */

4. Read through allegro.txt, skipping any sections that
completely confuse you.
5. Download DOSArena from Damian Yerrick's home
page. It contains an example of how to write and draw
a complete game suite with Allegro.
