My April 1997 Garbage In / Garbage Out column from ACM Sigplan Notices is
now online at:
ftp://ftp.netcom.com/pub/hb/hbaker/sigplannotices/gigo-1997-04.html
(Some browsers can't access ftp.netcom.com from behind a proxy firewall.
Netcom won't fix this anytime soon. Old-style ftp access may still work.
Sorry about this, but there's nothing I can do about it right now.)
