- Judges' comments:
-
- The addition of trigraphs has made it easier to make programs
- hard to read. It was a dark and stormy night for C when the
- ANSI C committee added trigraphs to the standard. Too bad
- that they didn't just simply require a more reasonable ISO
- character set.
-
- The common.mk (non-ANSI) makefile uses sed to form scjones.alt.c.
- The scjones.alt.c is similar to the original scjones.c source,
- but with all the trigraphs converted. You might want to try:
-
- make -f common.mk scjones.alt.c
-
- even if you only have an ANSI compiler, just to see how
- the trigrapsh are converted.
-
- WARNING: In the future, we will be passing ANSI programs through a
- trigraph filter before reading. Trigraph-ifacation will
- not be a major consideration in future contests. People
- should exploit more interesting features of ANSI C.

- Selected notes from the author:
-
- Since this year's contest is dedicated to ANSI C, here is a
- strictly conforming entry. In accordance with the ANSI
- definition of a strictly conforming program it does not produce
- output dependent on any unspecified, undefined, or implementation
- defined behavior, and it does not exceed any of the minimum
- implementation limits. It adheres to all of the syntactic and
- semantic constraints of the standard, #includes the relevant
- headers for the functions it uses, and uses the EXIT_SUCCESS and
- EXIT_FAILURE macros to return a correct success/fail status to
- the invoking program. It also uses trigraphs for characters
- which are not in the Invariant Code Set of ISO 646:1983, so it
- will be portable to machines with deficient (from C's standpoint)
- character sets. In short, it should be very widely portable. As
- an extra added attraction, all of the lines are under 72
- characters long, which would allow for sequence numbers to be
- punched in columns 73-80 :-).

- Although I am quite grateful for the "ANSI Committee's Worst Abuse
- of C" title (were you aware that I am a member of the committee or
- is the double meaning unintentional?), I was really hoping for
- something more along the lines of "Closest Resemblance to Line Noise." :-)
