These little doo-hickies will be a familiar nightmare to anyone that has worked in the US Antarctic Program. All are DOS based, all are highly outdated and all are very confusing. Yet we use these programs year after year, and honestly, the whole Antarctic program would probably crash and burn without them. Part of the most recent contract negotiations included replacing AREV. This never happened and I'm sure this will be brought up again when the new contract is rewarded next year.
