GO

  The constant is defined either through the compiler invocation:

                  cc  prog.c  -DCLEAR = 12

   or in the program itself:

                   #define   CLEAR   12

                    main()

                    {

                        mesg = CLEAR;

                        putchar(mesg);     /* clear screen   */

                    }

   The resulting effect in the program is shown above.

                       putchar(12);
