>>> lots of people writing about falling thru a case inside a switch() <<<

A trick I use (as seen in some BSD code :-) is:
	
#define when	break; case

	switch( ch ) {
	    case 'A':	doa();
	    when 'B':   dob();
	    when 'C':   seenc = 1;
	    /* FALLTHROUGH */
	    case 'D':	doocd( seenc );
         }

It cleans up the code a bit, I think.
