A good way to make your code a little more portable (note the use of the
relative term as opposed to the absolute) is to encapsulate the pointer
type...

If you have some oft-included header file (call it <generic.h>), insert a
typedef such as
     typedef void far *     genptr;

Choose the identifier to suit yourself and your coding style... then you can
write
      printf("Address of foob is [%p] \n", (genptr)&foob);

If you move to another implementation, you only have to change the typedef.
  [Obviously, in this instance, you'll have to do more than that,
   since there's not a '%p' format specifier in the ANSI printf()!!!
   Sorry.  :-/ ]
