3000's use in 2028: bug, or feature?
April 30, 2012
The CALENDAR intrinsic that blocks HP 3000 use in 2028 has been described as a bug. On the first day of that year, dates will not be represented accurately. Some in your community consider that New Year's Day, less than 16 years from now, as the 3000's final barrier. But it depends on how you look at it -- as a veteran, or a voyager.
A voyager sees CALENDAR as a deadline for departure. This is a part of MPE that was designed in the 1970s, a period when HP had just scrapped a 32-bit release of the 3000's first OS. And just like the Y2K date design, HP engineers never figured their server's OS had any shot of working by the 21st Century -- let alone 2027. But VEsoft's Vladimir Volokh says, "It's difficult to predict anything, especially the future." An IT pro who's planning to depart the 3000 believes CALENDAR is a bug, but that's not how Vladimir sees it.
"This is not a bug, really," he said. "It's a limitation. The end of 2027 date was as far away as infinity when MPE was created." This is a man who defines the term veteran, the kind of professionals who had to work inside 4K memory spaces to build 3000 programs. Limited and expensive resources like memory and disc were supposed to be extended with newer computers. "Every analyst told us a computer would live five years, at most," Vladimir said.
But as a veteran, you've now come to see the day when MPE's lifespan is reaching eight times that prediction. The veteran who chooses to see CALENDAR as a limitation can refer to HP's own lab response. Engineers during the '90s built HPCALENDAR to start extending the 3000's date limits.
