 statementsAndDeclarations

Description   A Turing program consists of a list of statements and declarations.

Example   This is a complete Turing program. It outputs Alan M. Turing.

        put "Alan M. Turing"
Example   This is a complete Turing program. It outputs a triangle of stars.

        var stars : string := "*"
        loop
            put stars
            stars := stars + "*"
        end loop
Example   This is a complete Turing program. It outputs Hello once and Goodbye twice.

        procedure sayItAgain ( what : string, n : int )
            for i : 1 .. n
                put what
            end for
        end sayItAgain
        
        sayItAgain ( "Hello", 1)
        sayItAgain ( "Goodbye", 2 )
Details   In a program there can be many units (see unit), one of which is the program (called the main program), the others of which are modules, monitors and classes. The main program is optionally preceded by an import list, which lists the units that it uses.
