The flow charts describe an algorithm for shift operations, useful in connection with systems such as the IBM Series/1 computers. The advantage include exclusion of specialized hardware for shift operations, a common rotate routine for all shift operations, and a specific check to insure that high shift counts do not result in high execution times.
