   Assuming that the data type is a CARDINAL then try the following:
 
   a = b XOR c                                          ; pseudo code

   a := CARDINAL(BITSET(b)/BITSET(c));                  ; Modula-2
 
 
By using a type transfer to convert the data into a set, set operations 
can then be applied. Following the operation, a type transfer is used 
to convert back to the original type.
 
When I use set operations, I usually use SETs in the first place since 
technically the operations are set operations.
