The standard allows integers to be cast to pointers, though the result is
implementation-defined.  Consider something like:
  char *BASE_IN;
  BASE_IN = (char *) 7000;
  fread (BASE_IN, whatever_size, 1, whatever_file);
(Or if you meant 7000 as a hexadecimal address then say 0x7000.)

>THEN READ IT .. PROCESS IT... THEN WRITE TO MEMEORY AT BASE_OUT=10000

  char some_char;
  char *BASE_OUT;
  BASE_OUT = 10000;
  some_char = *BASE_IN;
  *BASE_OUT = process(some_char);

If this were the company's opinion, I wouldn't be allowed to post it.
Pardon me?  Or do I have to commit a crime first?
