Does anybody know where I can get some sample code for doing 
raycasting using djgpp and allegro, written in c.I have been working in 
Borland for about 6 mo. and switching over to djgpp and allegro has got 
me lost.I am used to calling far pointers in Borland - char far *screen 
=(char far *) MK_FP(0xa000,0).Most of what I have learned came from 
"Gardens of Imagination" & "Tricks - - game programming gurus".I 
understand this code well but porting it to djgpp/allegro has me.I want 
to use as much of allegro as possible.
      I read up on sys/fptr but that just didn't help..I don't have 
enough hair left on my head to pull out.
       
     HELP ME PLEASE.............  LAB
