I have a constant defined, lets call it A:
#define A 1
I want to have another constant defined called be such that B=A+2 so you could 
do:
#define B A+2

The issue is that I need B to be computed as the value of A+2, not as "A+2" 
which will be directly plugged into code where ever B is referenced. Is there 
any way to define a token as the combined value of numbers?

The reason I need this is because I use the definition in assembly as well as 
c, and '+' isn't too assembly friendly.
