Tiny is an extremely simple programming language

Programming language

A programming language is an artificial language designed to communicate instructions to a machine, particularly a computer. Programming languages can be used to create programs that control the behavior of a machine and/or to express algorithms precisely....

techniques to students.

The language itself is so basic that it only includes reading of integer numbers, addition and subtraction arithmetic operations, and displaying numerical values.

The grammar of the language follows:

        -> BEGIN  END

      ->   | 

           ->  := ;

           -> READ (  ) ;

           -> WRITE (  ) ;

        -> ,  | 

      -> ,  | 

           ->    | 

         -> (  ) |  | INT

             -> + | -

          -> ID

As can be deduced from this simplistic grammar, the language is of limited practical use, gaining the most value as a teaching aid.
