+<p>The C startup routine (via crt0.o) transfers control to a location
+named main.  In this case, main just happens to be in the data area.
+The array of shorts, which has been further obfuscated by use of
+different data types, just happens to form a meaningful set of PDP-11
+and Vax instructions.  The first word is a PDP-11 branch instruction
+that branches to the rest of the PDP code.  On the Vax main is called with
+the calls instruction which uses the first word of the subroutine as a
+mask of registers to be saved.  So on the Vax the first word can be anything.
+The real Vax code starts with the second word.  This small program
+makes direct calls to the write() Unix system call to produce a
+message on the screen.  Can you guess what is printed?  We knew you
+couldn&rsquo;t!  :-)</p>
