Without question, this C program is one of the most obfuscated -C program that has ever been received! Like all great contest -entries, they result in a change of rules for the following year. -To prevent a flood of similar 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 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’t! :-)
