for ex.
            @array=(12300,archive) #array can contain list of values not only tow values. 
           like num_rows =>('12300','archive') # values shud be in teh same format as typed  with in single quotes 
 what i want to do with this is i have some statement which has num_rows so where it finds that key name it has to be replaced with all values in a key in that statement.
     like  update table set rows=&num_rows& 
then the replaced stmt shud b like
           update table set rows='12300','archive' #just an example
          its not that i want to do this only with key and value if we can do in any better idea than hash would be really great.
