In posting<1370@ism780c.UUCP>, Tim Smith asks about a switch with common
code for some cases.

While not necessarily the most efficient method, I think nested switches
are prefered in this situation over goto's.  Notice the inner switch need
not be concerned with 'case A', 'case E', or 'default' since 'thing' has
already been tested in the outer switch.

	switch(thing) {
	case A: A-code; break;
	case B:
	case C:
	case D: switch(thing) {
	        case B: B-code; break;
	        case C: C-code; break;
	        case D: D-code; break;
	        }
                BCD-common-code;
                break;
	case E: E-code; break;
	}
