  Let's take a closer look at the preceding example.
   #ifdef   VAX
        wordsize = 32;
   #else
        wordsize = 16;
   #ifndef MC68000
        clib = "/usr/lib/common";
   #else    /* for #ifndef   */
        clib = "/usr/lib/mc68";
   #endif      /* for #infndef  */
   #endif      /* for #ifdef    */
  If the constant MC6800 is defined, and the constant VAX is undefined,
  the effect is as shown on the following screen.
   #ifdef   VAX
        wordsize = 32;
   #else
        wordsize = 16; 
   #ifndef MC68000
        clib = "/usr/lib/common";
   #else    /* for #ifndef   */
        clib = "/usr/lib/mc68"; 
   #endif      /* for #infndef  */
   #endif      /* for #ifdef    */

  compiled are highlighted!
