-- The example below shows the Oracle 11g PL/SQL CONTINUE feature that 
-- can be used to loop forward when a CONTINUE statement condition 
-- evaluates to be true.  In the example below, the SQRT() function
-- is computed only when the continue statement condition is true.
-- The base index value (i_val) and post continue index value (i_idx)
-- are displayed only after continue statement condition evaluates to
-- false.  The i_idx gets incremented only after continue statement
-- evaluates to false.

-- Without the CONTINUE statement, both i_val and i_idx would have 
-- looped to reach the same values (based on i_max - computed by the
-- random value).
