 First maintain a bit table, something that your code can reference as 
Bools via bit operations..
 In your case it's more less simple..
 
 A combine of 3 bits gives you the value of 7 this this can be used as 
the OR operation
  
 AND operation.
   If value = 7 then.....

 OR Operation.

  If Value <> 0 then....

 Xor Operation, 
  If Value in [1,2,4] then....

 If you need to build the "Value" Product from dangling booleans.

 Value := (Value Shl 1) OR Byte(YourBool); 
 
 Since the compiler only uses the first bit for native booleans this 
works out.
 
 Do the above for all three bools to build a final value..

 Or you can simply mask off a bit as your boolean value from a VALUE
location, which makes it faster in the longrun...

Does that do anything for you ?
