to                       Allows FOR Loops to Count Forward

 for <index> := <start> to <finish> do
   <statement>;

    The TO keyword is used when you want the index variable in a FOR loop
    to be incremented (going from a low to a high value).

            <index>   Any declared ordinal (Integer, Char, Boolean,
                      enumerated) variable.

   <start>,<finish>   Any expression of the same type as <index>.

        <statement>   Any legal statement; for multiple statements, use a
                      compound statement.
