How to define it as a macro?

Question

case MAP_KEY3:
case MAP_KEY4:
case MAP_KEY5:
case MAP_KEY6:
    break;
default:
    LampShow(LampID, 0);
    LampShow(LampID, 2);
    LampShow(LampID, 0);
    break;

I want to make a MARCO of above code so that I can use it anywhere repeatedly. But how to do? It is for C language.

If I do it like below:

#define AAA /
    case MAP_KEY3:  /
    case MAP_KEY4:  /
    case MAP_KEY5:  /
    case MAP_KEY6:  /
        break;      /
    default:        /
        LampShow(LampID, 0);   /
        LampShow(LampID, 2);   /
        LampShow(LampID, 0);   /
        break;

Then I will got this error:

34: syntax error before `case'

line 34 is case MAP_KEY3: /

That's what functions are for.
