It may not be quite as simple as you think.  How do you know if you are
looking at code, data or random garbage?  What you want is a superset
of a disassembler and those generally need a lot of user interventioon.

Consider the following:  (This is based on actual code)

   ...
   call print
   db   'Hello, world', CR, LF, 0
   mov  a, b
   ...

The print function would pull the string off the stack, print it and adjust
the stack pointer before returning.  How would you determine the start of
data there and if you did how would you know where it ended?  If you are
lucky someone has already written what you want.  If not, this is not a
knock-off project by any means.
