OVERVIEW
 
          Counters are like very simple variables that can be incremented, decremented, and cleared.
 
          The Scout provides two counters (0 and 1).
 
          The RCX2 provides three counters (0, 1, and 2). In the case of RCX2, these counters are overlapped with global storage locations 0-2, so if they are going to be used as counters, a #pragma reserve should be used to prevent NQC from using the storage location for a regular variable. For example, to use counter 1: 
  #pragma reserve 1
