The syntax for djgpp's asm is at&t style... you'll have to learn to use
it...or use nasm.. although at&t's it's not much different from
intels...pretty much just flip the source and dest.
to use asm you'll need to use:

asm("code goes here with \n separating each
line":outputs:intputs:modified registers/flags);

thats about it....
