The Grand Prize: <vu44!{sjoerd,cogito}> Sjoerd Mullender & Robbert van RenesseWithout question, this C program is the most obfuscated C program thathas ever been received!  Like all great contest entries, they resultin a change of rules for the following year.  To prevent a flood ofsimilar programs, we requested that programs be non machine specific.This program was selected for the 1987 t-shirt collection.NOTE: If your machine is not a Vax-11 or pdp-11, this program will      not execute correctly.  In later years, machine dependent      code was discouraged.The C startup routine (via crt0.o) transfers control to a locationnamed main.  In this case, main just happens to be in the data area.The array of shorts, which has been further obfuscated by use ofdifferent data types, just happens to form a meaningful set of PDP-11and Vax instructions.  The first word is a PDP-11 branch instructionthat branches to the rest of the PDP code.  On the Vax main is called withthe calls instruction which uses the first word of the subroutine as amask 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 programmakes direct calls to the write() Unix system call to produce amessage on the screen.  Can you guess what is printed?  We knew youcouldn't!  :-)
