you sure you''ve got the opening of the asm block right?
on VS.Net its __asm{.. assmbler here.. }

i just solved it through google.
Turbo C++ lets you write assembly language code right inside your C and C++ programs. This is known as inline assembly and has certain restrictions.
It cannot use assembler macros
It cannot handle 80386 or 80486 instructions
It does not permit Ideal mode syntax
It allows only a limited set of assembler directives

yes i did hav it right read the above post
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
EDIT:could someone port that assmembly to c?

if you are using turbo C, just use #include <vesa.h> and the vesa.bgi drivers (you''ll have to download them seperately, they weren''t in the first distribution - atleast not on the ones I had).
and you should try __asm, not asm. Same goes for the other versions of borland C/C++/builder etc.
I haven''t got version 2.0 installed anymore, but it works fine in the 5.5 compiler.
