 *  3. Operand Type (counted once per operand reference):
 *  ---------------
 *                          number    approximate
 *                                    percentage
 *
 *     Integer               175        72.3 %
 *     Character              45        18.6 %
 *     Pointer                12         5.0 %
 *     String30                6         2.5 %
 *     Array                   2         0.8 %
 *     Record                  2         0.8 %
 *                           ---       -------
 *                           242       100.0 %
 *
 *  When there is an access path leading to the final operand (e.g. a record
 *  component), only the final data type on the access path is counted.
 *
 *
 *  4. Operand Locality:
 *  -------------------
 *                                number    approximate
 *                                          percentage
 *
 *     local variable              114        47.1 %
 *     global variable              22         9.1 %
 *     parameter                    45        18.6 %
 *        value                     23         9.5 %
 *        reference                 22         9.1 %
 *     function result               6         2.5 %
 *     constant                     55        22.7 %
 *                                 ---       -------
 *                                 242       100.0 %
 *
 *
 *  The program does not compute anything meaningful, but it is syntactically
 *  and semantically correct. All variables have a value assigned to them
 *  before they are used as a source operand.
 *
 *  There has been no explicit effort to account for the effects of a
 *  cache, or to balance the use of long or short displacements for code or
 *  data.
