note; scripting dictionary is  just like a two-dimentional array:
         scrpting dictionary is just like a small table having only two fields.
         The scripting dictionary looks like this:

          KEY    ITEM
          -----------------
            23      Ramesh
            35      Peter
            40      Sam

For example, if you want to create a table during the intial stage of a program.
Then, use this table in the middle
And finally delete the table.
