  Yes, but the portability is mostly an illusion in this case. Since Unix is 
a multitasking operating system, exec() is most commonly used with fork(), 
another Posix.1 function. DOS/Win16 have no equivalents to fork() and, IIRC, 
even Win32 has no directly portable fork() function.
  Other folks feel free to jump in and correct me if I'm wrong...
