[c-prog] Compile ASM code in C++ application

[gsronline]

Hi

I am converting an application from VS6 to VS7 (vs2003). There are some 
code which are asm. When I am trying to compile the files, its throwing 
errors. please let me know how to tell the compiler to treat them as ASM

eg:
#define BREAK   asm __volatile__ (" break ");

//compiler throws this error: 
error C2061: syntax error : identifier '__volatile__'

thanks
Rajesh
