+If the constant 0 is to be used as an argument to any of the case 
+statements, using it as the first argument of the first case statement 
+will produce slightly more efficient code.

 Example:
   puts("You pressed ");
   select (getc()) {
+    case $00: putln("Nothing");
     case $0D: putln("The Enter key");
     case ' ': putln("The space bar");

+Unlike the switch statement in C, the break statement is not needed to 
+exit from a case block. It may be used, however, to prematurely exit a 
+case block if desired.

+Example:

 Note: It's possible for multiple case statement arguments to evaluate to
 the same value. In this case, only the first case block matching the
 select expression will be executed.
