_asm inside a #define

In MSVC 4.1 I can write the following code

      __asm {
            jb 0x01
            jb 0xf9
      }

If however I put it into a macro:-

#define OB3 __asm { \
      jb 01 \
      jb 0xf9 \
}

and then use the macro in my code:-

OB3;

I get an error on each use of the macro.

warning E4405 warning 'jb' is a reserved word
error C2400 inline assembler syntax error in 'first operator'; found 'constant'.

This seems to happen with any assembler I create. How can I generate assembler within a macro?

What about the semicolon after the macro?

The problem is that the macro evaluates to a single line, i.e. __asm { jb 01 jb 0xf9}. Try
#define OB3\
__asm { jb 01}; \
__asm { jb 0xf9 };
