signed short  position;

switch (position)
{
   case ( 500 to 1250)
   {
         /* set some variable */
         break;
   }

   case (100 to 499)
   {
         /* set some variable */
        break;
   }

   case (-200 to 99)
   {
        /* set some variable */
       break;
   }

   default:
   {
       /* set some variable */
       break;
   }
}

If not, what other constructs can be used besides if - else ?

No.  

The C switch statement requires exact values, though you can place multiple values in the same block.

For what you're describing, the structure

  if () else if ()

is probably the best.

Sure, but it probably doesn't translate well to as many values as your example suggests

switch (Status)
{
  case 0:
  case 1:
  case 12:
    do_something ();
    break;

  case 2:
  case 11:
    do_something_else ();
    break;

  default:
//    do_nothing ();
    break;
}

I don't know that there's a limit to the number of times that case case occur in a switch statement, but the practical limit is probably a lot smaller than the language or architecture limit.
