Since the possibility of the tablename being a variable exists, why not obtain a count from user_tables. This way, the extra hassle of using the dbms_sql package is eliminated.

SELECT count(*)

   INTO RecCount
   FROM user_tables
  WHERE table_name = {VARCHAR2(50) table_name variable};

No exceptions would be thrown using this mechanism, therefore it also reduces the number of begin...end blocks being handled. This reduction makes the code far more readable and maintainable.
