 hi !
 
 It will be much easier to type:
   __asm__ ("
    movl $99,%ebx
    shll $8,%ebx
      .......
  ");
 
 Then you dont need extra sux characters at the endofline.

Archee,

Thanks for that, but I think you should know I just ripped a few lines of
inline out of a larger module.... just to show what it looked like....

... the code is from my attempt to turn a C "sliver renderer" for a wolf3d
type engine I made, into djgpp's inline asm....

 - I was never able to implement it, because, even though I could get a hold
of my double_buffer's memory AND the texturemap -> I wasn't able to figure out
how, or what I had left over, to point to a triangular array I have set up to
"premap" scales for my textures - and extract the right y (texture coordinate)
...

I don't think it's as much a problem w/ intel syntax as it is my own problem
knowing the inner workings of my machine ; )

Hopefully after I take assembly next semester, I'll be able to convert the
c....

If the problem I'm having is unclear (and it is) let me know...

Jim

P.S.: Thanks again
