Reply-to: kg at elan.UUCP (Ken Greer) We ran into a problem today in that a program compiled on a Vax running Ultrix 2.3 got a "Bad System Call" and core dumped on a 4.3 BSD system. Anyone known what works and what doesn't? --- Ken Greer Elan Computer Group, Inc. {ames,hplabs,uunet}!elan!kg 415-322-2450
