 As best i know -- correct me if I am out of date -- neither Java 
 not C++ allows you to "case" a RANGE of constants.  
 
 I don't know which language does do that..... Pascal, maybe?


 The way you can get round it is have a function which changes these 
 ranges into a single number then "case" on that:

 class MyClass{
     //---
     static final int AtoZ = 128,
                      atoz = 129;
     //---
     void doSomething(c1){
         switch(mapChar(c1)){
             case '0': .......
             case '1': .......
             case '2': .......
             case AtoZ: ......
             case atoz: ......
         };
     };
     //----
     char macChar(char c1){
         ;;;; if('A'<=c1 && c1<='Z') then return AtoZ;
         else if('a'<=c1 && c1<='z') then return atoz;
         else if('0'<=c1 && c1<='9') then return c1;
         else if(c1 > 128          ) then return 0;
         else                             return c1; 
     };
 };
